Number of employees
Wang Laboratories was a computer company founded in 1951, by An Wang and G. Y. Chu. The company was successively headquartered in Cambridge, Massachusetts (1954–1963), Tewksbury, Massachusetts (1963–1976), and finally in Lowell, Massachusetts (1976–1997). At its peak in the 1980s, Wang Laboratories had annual revenues of $3 billion and employed over 33,000 people. It was one of the leading companies during the time of the Massachusetts Miracle.
The company was directed by An Wang, who was described as an "indispensable leader" and played a personal role in setting business and product strategy until his death in 1990. Under his direction, the company went through several distinct transitions between different product lines, beginning with typesetters, calculators and word processors, then adding computers, copiers and laser printers.
Wang Laboratories filed for bankruptcy protection in August 1992. After emerging from bankruptcy, the company eventually changed its name to Wang Global. Wang Global was acquired by Getronics of the Netherlands in 1999, becoming Getronics North America, then was sold to KPN in 2007 and CompuCom in 2008, after which it no longer existed as a distinct brand or division.
Public stock listing
An Wang took steps to ensure that the Wang family would retain control of the company even after going public. He created a second class of stock, class B, with higher dividends, but only one-tenth the voting power of class C. The public mostly bought class B shares; the Wang family retained most of the class C shares. (The letters B and C were used to ensure that brokerages would fill any Wang stock orders with class B shares unless class C was specifically requested). Wang stock had been listed in the New York Stock Exchange, but this maneuver was not quite acceptable under NYSE's rules, and Wang was forced to delist with NYSE and relist on the more liberal American Stock Exchange. After Wang's 1992 bankruptcy, holders of class B and C common stock were treated the same.
The company's first major project was the Linasec in 1964. It was an electronic special purpose computer, designed to justify papertape for use on automated Linotype machines. It was developed under contract to Compugraphic, who manufactured phototypesetters. Compugraphic retained the rights to manufacture the Linasec without royalty. They exercised these rights, effectively forcing Wang out of the market.
The Wang LOCI-2 Logarithmic Computing Instrument desktop calculator (the earlier LOCI-1 in September 1964 was not a real product) was introduced in January 1965. Using factor combining it was probably the first desktop calculator capable of computing logarithms, quite an achievement for a machine without any integrated circuits. The electronics included 1,275 discrete transistors. It actually performed multiplication by adding logarithms, and roundoff in the display conversion was noticeable: 2 times 2 yielded 3.999999999.
From 1965 to about 1971, Wang was a well-regarded calculator company. Wang calculators cost in the mid-four-figures, used Nixie tube readouts, performed transcendental functions, had varying degrees of programmability, and exploited magnetic core memory. The 200 and 300 calculator models were available as timeshared simultaneous (SE) packages that had a central processing unit (the size of a small suitcase) connected by cables leading to four individual desktop display/keyboard units. Competition included HP, which introduced the HP 9100A in 1968, and old-line calculator companies such as Monroe and Marchant.
Wang calculators were at first sold to scientists and engineers, but the company later won a solid niche in financial-services industries, which had previously relied on complicated printed tables for mortgages and annuities.
One perhaps apocryphal story tells of a banker who spot-checked a Wang calculator against a mortgage table and found a discrepancy. The calculator was right, the printed tables were wrong, and the company's reputation was made.
In the early seventies, Wang believed that calculators would become unprofitable low-margin commodities, and decided to exit the calculator business.
The Wang 1200
Wang's first attempt at a word processor was the Wang 1200, announced in late 1971, but not available until 1972. The design consisted of the logic of a Wang 500 calculator hooked up to an OEM-manufactured IBM Selectric typewriter for keying and printing, and dual cassette decks for storage. Harold Koplow, who had written the microcode for the Wang 700 (and its derivative, the Wang 500) rewrote the microcode to perform word processing functions instead of number crunching.
The operator of a Wang 1200 typed text on a conventional IBM Selectric keyboard; when the Return key was pressed, the line of text was stored on a cassette tape. One cassette held roughly 20 pages of text, and could be "played back" (e.g., the text retrieved) by printing the contents on continuous-form paper in the 1200 typewriter's "print" mode. The stored text could also be edited, using keys on a simple, six-key array. Basic editing functions included Insert, Delete, Skip (character, line), and so on.
The labor and cost savings of this device were immediate, and remarkable: pages of text no longer had to be retyped to correct simple errors, and projects could be worked on, stored, and then retrieved for use later on. The rudimentary Wang 1200 machine was the precursor of the Wang Office Information System (OIS), which revolutionized the way typing projects were performed in the American workplace.
Following the Wang 1200, Harold Koplow and David Moros made another attempt at designing a word processor. They started by first writing the user's manual for the product. A 2002 Boston Globe article refers to Koplow as a "wisecracking rebel" who "was waiting for dismissal when, in 1975, he developed the product that made computers popularly accessible."
In Koplow's words, "Dr. Wang kicked me out of marketing. I, along with Dave Moros was relegated to Long Range Planning — 'LRPed'. This ... was tantamount to being fired: 'here is a temporary job until you find another one in some other company.'"
Although he and Moros perceived the assignment to design a word processing machine as busywork, they went ahead anyway. They wrote the manual and convinced An Wang to turn it into a real project. The word processing machine – the Wang 1200 WPS – was introduced in June 1976 and was an instant success, as was its successor, the 1977 Wang OIS (Office Information System).
These products were technological breakthroughs. They were multi-user systems. Each workstation looked like a typical terminal, but contained its own Intel 8080 microprocessor (later versions used a Z80) and 64 KB of RAM (comparable, but lower in power than the original IBM PC which came out in 1981). Disk storage was centralized in a master unit and shared by the workstations, and connection was via high-speed dual coaxial cable "928 Link". Multiple OIS masters could be networked to each other, allowing file sharing among hundreds of users. The systems were user-friendly and fairly easy to administer, with the latter task often performed by office personnel, in an era when most machines required trained administrators.
Ahead of IBM and Xerox, the lead for "the 'intelligent' printer: a reasonably priced, high-speed office copier that can be linked electronically to ..." PCs "and other automated equipment" was captured by Wang. A year later The New York Times described the IBM 6670 Information Distributor as "closer to the standard envisioned."
Early computer models
Wang's first computer, the Wang 3300, is an 8-bit integrated circuit general purpose minicomputer specifically designed to be the central processor for a multi-terminal time-sharing system. Byte oriented it also provides a number of double byte operand memory commands. Core memory ranges from 4,096 to 65,536 bytes in 4,096 byte increments.
On its journey from calculators and word processing to serious data processing Wang developed and marketed several lines of small computer system, some of which were WordProcessing-based and some of which were DataProcessing-based. Instead of a clear, linear progression, the product lines overlapped and in some cases borrowed technology from each other.
The most identifiable Wang minicomputer performing recognizable data processing was the Wang 2200 which appeared in May 1973. Unlike some other desktop computers such as the HP 9830, it had a CRT in a cabinet that also included an integrated computer controlled Compact Cassette storage unit and keyboard. Microcoded to run interpretive BASIC, about 65,000 systems were shipped in its lifetime and it found wide use in small and medium-size businesses worldwide.
The original 2200 was a single user system. The improved VP model increased performance more than tenfold and enhanced the language (renamed Basic-2). The 2200 VP evolved into a desktop computer and larger MVP system to support up to 16 workstations and utilized commercial disk technologies that appeared in the late 1970s and early 1980s. The disk subsystems could be attached to up to 15 computers giving a theoretical upper limit of 240 workstations in a single cluster.
Unlike the other product lines such as the VS and OIS (both described below), Wang aggressively used value added resellers (VARs) to customize and market 2200 systems. One such creative solution deployed dozens of 2200 systems and was developed in conjunction with Hawaii- and Hong Kong-based firm, Algorithms, Inc. It provided paging (beeper) services for much of the Hong Kong market in the early 1980s.
Overshadowed by the Wang VS, the 2200 languished as a cost-effective, but forgotten solution in the hands of the customers who had it. In the late 1980s Wang revisited the 2200 series one last time, offering 2200 customers a new 2200 CS with bundled maintenance for less than customers were then paying just for maintenance of their aging 2200s. The 2200 CS was accompanied by an Intel 386 processor, updated disk units and other peripherals. Most 2200 customers upgraded to the 2200 CS, after which Wang never again developed or marketed any new 2200 products. In 1997, Wang reported having about two hundred 2200 systems still under maintenance around the world. Throughout, Wang had always offered maintenance services for the 2200.
The 2200 Basic2 language was ported to be compiled and run on non-Wang hardware and operating systems by at least two companies. Niakwa Inc created a product named NPL (originally named Basic-2C). Kerridge Computer (now a part of ADP) created a product named KCML. Both products support DOS, Windows and various Unix systems. The Basic2 language has been substantially enhanced and extended by both companies to meet modern needs. Compared to the 2200 Wang hardware the compiled solutions improve all factors (speed, disk space, memory, user limits) by tens to hundreds of times. So while Wang support for the 2200 is gone many software applications continue to function.
During the 1970s about 2,000 Wang 2200T computers were shipped to the USSR. Due to the Afghan war in the 1980s, US and COCOM export restrictions ended the shipment of Wang computers. The Soviets were in great need of computers. In 1981 Russian engineers at Minpribor's Schetmash factory in Kursk reverse engineered the Wang 2200T and created a computer they named the Iskra 226. The "COCOM restrictions" theory, though, while popular in the West, is challenged by some Russian computer historians on the basis of the fact that development for the Iskra-226 started in 1978, two years before the Afghan war. One possible reason for this might be a Soviet fear of the backdoors in the Western hardware. It is also significantly different from the Wang 2200 in its internals, being more inspired by it, rather than a direct clone.
It used the same Basic language (named T-Basic) with a few enhancements. Many research papers reference calculations done on the Iskra 226. The machine's designers were nominated for a 1985 State Prize. Later, a somewhat scaled-down Unix implementation was created for Iskra-226, which was widely used in the Soviet Union but is virtually unknown in the West.
Wang had a line called Alliance, which was based on the high end OIS (140/145) hardware architecture. It had more powerful software compared to the OIS word processing and list processing packages. The system was Tempest certified, leading to global deployment in American embassies after the Iran hostage crisis. The Z80 platform on which Alliance ran forced it to remain as an 8-bit application in a 64 KB workstation.
The Wang VS computer line
The first Wang VS computer was introduced in 1977, the same year as Digital Equipment Corporation's VAX; both continued for decades. The VS instruction set was compatible with the IBM 360 series, but it did not run any IBM 360 system software.
The VS operating system and all system software were built from the ground up to support interactive users as well as batch operations. The VS was aimed directly at the business data processing market in general, and IBM in particular. While many programming languages were available, the VS was typically programmed in COBOL. Other languages supported in the VS integrated development environment included Assembler, COBOL 74, COBOL 85, BASIC, Ada, RPG II, C, PL/I, FORTRAN, Glossary, MABASIC, SPEED II and Procedure (a scripting language). Pascal was also supported for I/O co-processor development. The Wang PACE (Professional Application Creation Environment) 4GL and database was used from the mid-1980s onward by customers and third-party developers to build complex applications sometimes involving many thousands of screens, hundreds of distinct application modules, and serving many hundreds of users. Substantial vertical applications were developed for the Wang VS by third-party software houses throughout the 1980s in COBOL, PACE, BASIC, PL/I and RPG II. The Wang OFFICE family of applications and Wang WP were both popular applications on the VS. Word Processing ran on the VS through services that emulated the OIS environment and downloaded the WP software as "microcode" (in Wang terminology) to VS workstations.
The press and the industry referred to the class of machines made by Wang, including the VS, as "minicomputers," and Kenney's 1992 book refers to the VS line as "minicomputers" throughout. Although some argue that the high-end VSes and their successors should qualify as mainframes, Wang avoided this term. In his autobiography, An Wang, rather than calling the VS 300 a mainframe, said that it "verges on mainframe performance". He went on to draw distinction between the "mainframes" at the high end of IBM's line ("just as Detroit would rather sell large cars ... so IBM would rather sell mainframes")—in which IBM had a virtual monopoly—with the "mid-sized systems" in which IBM had not achieved dominance: "The minicomputer market is still healthy. This is good for the customer and good for minicomputer makers."
- The VS7000 was introduced in 1987. These were a renumbering of the VS100, and VS300, with their more powerful counterpart upgrades identified as VS7110, VS7120 and VS7130 (for the VS100) and the VS7310 as the new high-end machine in this series.
- Later models, the small VS5000 series, launched in approximately 1988, were user-installable, the smallest being physically similar in size to PCs of the era.
- The largest iteration, the VS10000 supported an increasingly substantial number of users. The VS10000 was a technological departure from earlier models, in that it used "emitter coupled logic" (ECL). ECL is a very fast current based logic that necessitated the use of very large 375 amp, 3 volt power supplies, massive heat-sinks and large squirrel cage blowers. It was stated that the VS1000 computer drew up to ten kilowatts of power. For anyone who serviced these devices, the most comfortable place (also the noisiest) in the computer room was behind the computer. It also led to embarrassing situations where the horizontally mounted CPU and memory boards often were allowed to contact the lower cage mount when withdrawn due to the significant weight of the board not being properly held on withdrawal.
The VS1000 was designed to run multiple concurrent operating systems, and was piloted with the VS ver7 and a Unix operating system, with strong rumors of a Novell research group attempting to rough a design for a large enterprise Novell OS.
Going after IBM
An Wang felt a personal sense of rivalry with IBM, partly as a result of heavy-handed treatment by IBM in 1955/56 over the rights to his magnetic-core patents. (This encounter formed the subject of a long chapter in Wang's own book, Lessons.) According to Charles C. Kenney, "Jack Connors remembers being in Wang's office one day when the Doctor pulled out a chart on which he had plotted Wang's growth and projected that Wang Laboratories would overtake IBM sometime in the middle of the 1990s. 'He had kept it a long time,' says Connors. 'And he believed it.'"
Wang was one of the first computer companies to advertise on television, and the first to run an ad during the Super Bowl in 1978. Their first ad literally cast Wang Laboratories as David and IBM as Goliath, several years before the famous 1984 Apple Computer ad. A later ad depicted Wang Laboratories as a helicopter gunship taking aim at IBM.
Wang wanted to compete against IBM as a computer company, selling directly to management information system departments. Before the VS, however, Wang Laboratories was not taken seriously as a computer company. The calculators, word processing systems and OIS were sold into individual departments, bypassing the corporate data-processing decision-makers. The chapter in Wang's book dealing with them shows that he saw them only as "a beachhead in the Fortune 1000." The Wang VS was Wang's entry into IT departments. In his book, An Wang notes that, to sell the VS, "we aggressively recruited salesmen with strong backgrounds in data processing ... who had experience dealing with MIS executives, and who knew their way around Fortune 1000 companies." As the VS took hold, the word processor and OIS lines were phased out. The word processing software continued, in the form of a loadable-microcode environment that allowed VS workstations to take on the behavior of traditional Wang WP terminals to operate with the VS and use it as a document server.
Wang made inroads into IBM and DEC markets in the 1980s, but did not have a serious impact on IBM's mainframe market due to self-limiting factors. Even though An Wang wanted to compete with IBM, too many Wang salespeople were incompletely trained on the significant DP capabilities of the VS. In many instances the VS ran smaller enterprises up to about $500 million/year and in larger organizations found use as a gateway to larger corporate mainframes, handling workstation pass-through and massive print services.
At Exxon Corporation, for instance, thirteen 1985 top-of-the-line VS300s at the Houston headquarters were used in the 1980s and into the 1990s to receive mainframe reports and make them viewable online by executives.
At Mellon Mortgage 18 VS systems from the smallest to the largest were used as the enterprise mortgage origination, servicing, finance, documentation and hedge system and also for mainframe gateway services for logon and printing. Between Mellon Mortgage and parent Mellon Bank, their network contained 45 VS systems and the Bank portion of the network supported about 16,000 Wang Office users for email, report distribution and scheduling.
At Kent and KTec Electronics, two related Houston companies, separate VS clusters were the enterprise systems, handling distribution, manufacturing and accounting, with significant EDI capability for receiving customer forecasts, sending invoices, and sending purchase orders and receiving shipping notifications. Both systems ran the GEISCO EDI package. Kent, which grew to $600 million/year, ran the Arcus distribution software in COBOL and KTec, which grew to $250 million/year, ran the CAELUS MRP system for manufacturing in BASIC.
In the late 1980s, a British television documentary accused the company of targeting a competitor, Canadian company AES Wordplex, in an attempt to take it out of the market. However, the documentary came to no conclusion regarding this.
Wang's approach was internally called "The Gas Cooker Program", named after similar programs to give discounts on new gas stoves by trading in an old one. Wang was accused of targeting Wordplex by offering a large discount on Wang OIS systems with a trade-in of Wordplex machines, regardless of the age or condition of the trade-in machine.
Based on its good reputation with users and its program of aggressive discounts, Wang gained an increasing share of a shrinking market. Wordplex was subsequently taken over by Norsk Data.
Word processing market collapse
The market for standalone word processing systems collapsed with the introduction of the personal computer. MultiMate, on the IBM PC and MS-DOS PC clones, replicated the keyboard and screen interface and functions of the Wang word processor, and was actively marketed to Wang corporate users, while several other WYSIWYG word processing programs also became popular.
Wang did make one last play in this arena, producing a dedicated Intel-based word processor called the Wang Office Assistant in 1984. This was marketed and sold very successfully in the UK to a specific few office equipment dealers who were able to upgrade their clients from electronic typewriters to the Office Assistant. They proved to be very reliable and fast when connected to the Wang bi-directional printer providing fairly cheap but very fast word processing to small companies such as Solicitors. The USA were surprised at the success of this machine in the UK but could not supply a spell check programme in time before the PC, with its flexibility of combining word processors with other programs such as spreadsheets, had rendered such a specific task machine largely unsellable. And so the Wang Office Assistant had a short life span of only four years.
The Digital Voice Exchange
The Wang DVX was one of the first integrated switchboard and voicemail systems. In the United Kingdom it was selected for the DTI Office Automation Pilot schemes at the National Coal Board in about 1980.
Internal research on speech recognition was carried out and implemented for discrete word recognition but was never released to the field. At one point there were 50 members of the Voice Engineering Department.
Lawrence E. Bergeron was instrumental in managing the Voice Engineering Department at Wang Labs. He promoted the purchase of a VAX-11/780 for 'real-time' signal processing research and created the Peripheral Signal Processor board (PSP). The PSP was placed into 16 racks to handle 128 phone lines for the DVX (Digital Voice Exchange). Wang's Digital Voice Exchange supported the renting of voice mailboxes. Voice prompts were created by a hired voice specialist to give a melodic presentation for the DVX. To avoid false triggering of touch-tones by the prompts (due to input/output cross talk), notch filters were created to remove the touch tone frequencies from the prompts.
Some of the prompt languages supported were: German, Spanish, French, British English, American English, and Portuguese.
PCs and PC-based products
Despite the release of the 2200 PCS (Personal Computer System) and 2200 PCS-II models as early as 1976, the history of computing regards the earliest PC as one which contained a microprocessor, which the 2200 PCS did not. However, the self-contained PCS-II incorporated many of the innovations that would later be seen in PCs, including the first 5.25-inch floppy drives that were especially designed for the PCS-II by Shugart Associates.
The original Wang PC
An Wang had initially refused to develop an IBM-compatible PC, due to his personal dislike of IBM, even though his son Fred had pitched the idea.
This article or section appears to contradict itself.(January 2021)
The original Wang PC was released April 1982 to counter the IBM PC which had been released the previous August and which had gained wide acceptance in the market for which Wang traditionally positioned the OIS system. It was based on the Intel 8086 microprocessor, a slightly faster CPU than the IBM PC's 8088. A hardware/software package that permitted the Wang PC to act as a terminal to the OIS and VS products was available. The hardware component, the first version was made of two large add-in boards called the WLOC (Wang Local Office Connection), contained a Z-80 processor and 64 KB of memory. The original PC-VS hardware was using the 928 terminal emulator board, the WLOC © boards were used in the subsequent 80286 machines.
These PC's later formed the basis for the system console on VS7000 and later series of the Wang mid frame series, being used for the initialisation of the boot process.
One of the distinguishing features of the Wang PC was the system software. Similar to the Wang VS minicomputer, the command line was not immediately evident. Everything could be run from menus, including formatting a disk. Furthermore, each item on a menu could be explained by hitting a dedicated Help key on the keyboard. This software was later sold in MS-DOS compatible form for non Wang hardware.
The Wang word processing software was also very graphical. The keyboard had 16 function-keys and, unlike WordStar, the popular word processor of the day, control key combinations were not required to navigate the system. The f-keys had the word processing functions labeled on them.
However, the biggest stumbling block was that – despite being a fully compliant MS-DOS system – it was not compatible with the IBM PC at the hardware level. This was a problem because MS-DOS was rarely used as anything more than a simple program loader; complex software (spreadsheets, Flight Simulator, etc.) could only obtain acceptable performance by direct manipulation of the hardware. Wang used a 16-bit data bus instead of the 8-bit data bus used by IBM, arguing that applications would run much faster since most operations required I/O (disk, screen, keyboard, printer). With this 16-bit design, Wang used peripheral hardware devices, such as the Wang PC display adapter, that were not compatible with their counterparts in the IBM PC line. This meant that the vast library of software available for the IBM PC could not be directly run on the Wang PC. Only those programs that were either written specifically for the Wang PC or ported from the IBM PC were available. A basic word processing package developed by Wang and Microsoft's Multiplan spreadsheet were the two commonly marketed software products. Lotus 1-2-3 and dBase II were also available. This dearth of application software led to the early demise of the original Wang PC, and it was replaced by an Intel 80286 based product that was fully plug compatible with the IBM PC. The unique system software was available at extra cost.
Most Wang PCs were released with a monochrome graphics adapter that supported a single video mode with text and graphics planes that could be scrolled independently, unlike IBM-compatible PCs of the time which required selecting a specific video mode to allow graphics. A color graphics adapter and Wang-branded color monitor were also available.
An ergonomic feature of the Wang PC was the monitor arm that clamped to the desk and held the monitor above and a system clamp that attached to the side of the desk and held the rather large computer box. By using these, there was nothing on the desktop except the keyboard.
IBM-compatible Wang PCs

After it became clear that it had been a mistake to ignore the issue of PC compatibility, Wang belatedly released an emulation board for Wang PC that enabled operation of many PC-compatible software packages. The board accomplished this by monitoring all I/O and memory transactions (visible in those days before North/South bridge chips to any board plugged into a slot on the expansion bus) and generating a non-maskable interrupt (NMI) whenever an operation was deemed to involve an incompatible device, requiring emulation.
For example: the floppy controller circuitry on the Wang PC was similar to that of the IBM PC but involved enough design differences that PC-compatible software attempting to manipulate it directly would fail. Wang's PC emulation hardware would detect I/O and memory operations involving the addresses associated with the floppy controller in the IBM PC and generate an NMI. The NMI handler would immediately be activated (the exception vector having been appropriated during system init to point to ROM routines on the emulation board instead of the NMI routine in the PC BIOS) and would then update an internal representation of the IBM PC floppy controller and manipulate the real controller to reflect its state. Reads were satisfied in a similar way, by forcing an NMI, decoding the machine code indicated by the instruction pointer at the time of the fault, and then obtaining the desired info and updating the CPU registers accordingly before resuming the executing program.
The PC emulation board thus enabled execution of an impressive number of applications by presenting "virtualized" PC-compatible hardware devices to them: a monochrome text-only video controller, a floppy controller, UARTs, DMA controller, parallel port, keyboard controller, etc.
IBM-PC Emulation on the 8086-based Wang PC was working fairly reliably when IBM released their 80286-based PC-AT. Wang's answer was the 80286-based Wang APC (Advanced Professional Computer) which not only perpetuated the PC incompatibility at the hardware level but revealed an unexpected wrinkle in the hitherto successful PC emulation strategy: the 8086 decoded and executed instructions on-the-fly and was therefore able to respond to NMI on every instruction boundary, but the 80286 decoded and queued instructions in a pipeline whose depth varied with each CPU-mask stepping but which always prevented timely NMI execution. Wang's engineers came up with (and later patented) a rather devious instruction-prefetch monitor that managed to cope with that challenge at the expense of a modest performance penalty.
Further iterations of the PC line were released commencing with the model number PC-240. These later models booted directly into MS-DOS (or another compatible operating system) and supported ISA-standard expansion cards.
This PC-240 still wasn't entirely IBM PC-standard as the keyboard, although being a standard PC/AT device, allowed for VS compatibility with 24 function keys rather than the normal 12, and a number of Wang VS-specific keys. There was also a slight difference in CPU interrupts from IBM standard, so some software had compatibility issues.
VS connectivity was via an ISA-based VS-terminal card, or via LightSpeed, the networked VS Terminal Emulator, over an IPX-based Ethernet connection. Originally the PC-240 came with a Wang-specific Hercules Graphics Card and compatible screen, which also acted as a keyboard extension, meaning the base unit could be kept some distance from the screen. This was later replaced with an EGA card and screen.
Around 1991, Wang released the PC350-16 and PC350-40, which were Intel 80386-based, clocked at 16 MHz and 40 MHz, respectively. They used the same VS-compatible keyboard as the PC-240. They had a maximum of 4 megabytes of RAM and came with VGA screens as standard. They were generally supplied with MS-DOS and Windows 3.0.
The 350-16 had an interesting[according to whom?] bug where, occasionally, the machine would freeze entirely and not boot up if power-cycled at the mains. Although it would power on, the BIOS wouldn't start. The solution was to turn on the machine at the mains and hold down the power button for 30 seconds, at which point it would normally start. It was suggested[by whom?] that this was due to an under-valued capacitor in the power circuit. This problem appeared to be resolved in the 350-40, which had a different PSU.
In 1992, Wang marketed a PC-compatible based on the Intel 80386SX processor, which they called the Alliance 750CD. It was clocked at 25 MHz and had a socket for an 80387 math coprocessor. It came with 2 megabytes of installed RAM, and was expandable to 16 megabytes using SIMM memory cards. It had a 1.44 megabyte floppy disk drive, an internal 80 megabyte hard disk, and a CD-ROM drive. Five expansion slots were built-in. It came with MS-DOS and Windows 3.1 operating systems.
In 1994, Wang released the slimline Alliance 750CD 80486 based PC in the United Kingdom. These machines used standard PC/AT keyboards and were entirely IBM compatible, shipping with MSDOS 5.0 and Windows 3.11 as standard. The only unusual feature was that system BIOS settings and the real-time clock were maintained by four standard AA batteries as opposed to a more typical solution – such as a specialty battery pack or lithium battery. While originally offered with a 33 MHz 80486DX, the 750CD could be upgraded to later Socket 3 processors such as the 80486DX2 through the use of third party CPU upgrade adapters or interposers. This allowed upgrading to speeds beyond 50 MHz without overclocking, or alternatively the potential for speeds in excess of 100 MHz with overclocking, dependent on the processor used.
- A touch-sensitive tablet and special stylus for written annotation of any file that could be displayed on the PC.
- A phone handset for voice annotation, but not voice communication. Demonstrated strongly in conjunction with the tablet for explaining the text annotations.
- Email, via Wang OFFICE, of the resulting document set.
Although the low end product was priced at $2,000 this precluded the important features such as "facsimile and voice options" (priced at $12,000). Freestyle was not a success in anything except marketing terms. A description of the system at the University of Southern California (USC) shows the symptoms of the failure:
The $1.2 million USC system includes a VS 7150 mid-range computer; 30 image workstations, 25 with Freestyle capabilities; a laser printer; five endorsers; and five document scanners. Initial storage for document images is eight gigabytes of magnetic disk storage.
Only 25 of the stations were Freestyle stations. The system was so costly, even in the context of a Wang Integrated Imaging System, that Freestyle was only affordable for highly specialized or very senior staff. Apart from USC, unusual in that it was deployed at clerical level, it was sold as a C-Level tool for C grades to communicate with other C Grades. This reduced the marketplace immediately from the mass market where the system would have been effective.
Decline and fall
Wang Labs would be only one of a large number of New England-based computer companies that would falter in the late 1980s and 1990s, marking the end of the Massachusetts Miracle. For instance the struggling Digital Equipment Corporation also significantly downsized in the 1990s and was acquired by Compaq.
A common view within the PC community is that Wang Labs failed because it specialized in computers designed specifically for word processing and did not foresee (and was unable to compete against) general-purpose personal computers with word processing software in the 1980s. Word processing was not actually the mainstay of Wang's business by the time desktop computers began to gain in popularity. Although Wang manufactured desktops, its main business by the 1980s, was its VS line of mini-computer and "midframe" systems. The market for these mini-computers was ultimately conquered by enhanced micro-computers like the Apple Macintosh and the "Wintel" PC on one end and Sun, IBM and Hewlett-Packard servers on the other end.
An Wang's insistence that his son, Fred Wang, succeed him contributed to the company's failure. Fred Wang was a business school graduate, "but by almost any definition", wrote Charles C. Kenney, "unsuited for the job in which his father had placed him". His assignment, first as head of research and development, then as president of the company, led to resignations by key R&D and business personnel. Amid declining revenues, John F. Cunningham, an 18-year employee of the firm, resigned as president and COO of Wang Labs to become chairman and chief executive of Computer Consoles Inc. Cunningham resigned due to disagreement with An Wang on how to pull the company out of the slump, as well as being upset that Fred Wang was positioned as the successor, an instance of nepotism.
One turning point occurred when Fred Wang was head of R&D. On October 4, 1983, Wang Laboratories announced fourteen major hardware and software products, and promised dates of delivery. The announcement was well received, but even at the time there were warning signs. According to Datamation, Wang announced "everything but the kitchen sink. And if you could attach the kitchen sink to a personal computer they would announce that too." Very few of the products were close to completion and many of them had not even been started. All were delivered late and some were never delivered at all. In retrospect this was referred to as the "vaporware announcement" and it hurt the credibility of Fred Wang and Wang Laboratories.
In 1986, Fred Wang, then 36 years old, was installed as president of Wang Laboratories. However, the company's fortunes continued to decline. Unlike most computer companies that funded their growth by issuing stock, An Wang had used debt to avoid further dilution of family control of the company. By August 1989, that debt was causing conflicts with its creditors. On August 4, 1989, An Wang fired his son. Richard W. Miller replaced him as the president of Wang Laboratories, having been with the company since 1988.
Miller announced in December 1989 that the company would start to embrace established software standards, rather than use traditional proprietary designs. An Wang died in March 1990, and Miller took on the additional posts of chairman and CEO. The company underwent massive restructuring, and in August 1990, it eliminated its bank debt, but still ended the year with a record net loss.
In November 1990, Wang announced their first personal computers running Unix. Previously, Wang's presence in the UNIX and open systems markets had been modest. In 1987, Wang developed a new typesetting system in conjunction with Arlington MA-based Texet Corp. The system used Xerox printers and UNIX workstations from Sun, but the product vanished before coming to market, partially because few Wang employees could use or support UNIX. UNIX ran on the VS – Interactive Systems first ported IN/ix (their IBM360 version of SYS5 UNIX) to run in a VSOS Virtual machine circa 1985, and then Wang engineers completed the port so that it ran "native" on the VS hardware soon thereafter – but performance was always sub-par as UNIX was never a good fit for the inherently batch-mode nature of the VS hardware, and the line-at-a-time processing approach taken by the VS workstations; indeed, the workstation code had to be largely rewritten to bundle up each keystroke into a frame to be sent back to the host when running UNIX so that "tty" style processing could be implemented. PACE, which offered its data dictionary, excellent referential integrity, and speedy application development, was in the process of being ported to UNIX under the name OPEN Pace. A client server RDBMS model, built on the original product's ideology, OPEN Pace was demonstrated at the North American PACE User Group Conferences in both Boston and Chicago. OPEN Pace, along with a new Windows-based word processor called UpWord (which was at the time considered a strong contender to retake Wang's original market leadership from Microsoft), were touted as their new direction. However, after a marketing study suggested that it would require large capital investments in order to be viable competitors against Microsoft, both products were simply abandoned.
Ira Magaziner, who was brought in by Miller in 1990, proposed to take Wang out of the manufacture of computers altogether, and to go big into imaging software instead. In March 1991, the company introduced its Office 2000 marketing strategy, focusing on office productivity.
In June 1991, Wang started reselling IBM computers, in exchange for IBM investing in Wang stock. Wang hardware strategy to re-sell IBM RS/6000s also included further pursuit of UNIX software.
Wang Laboratories filed for bankruptcy protection on August 18, 1992, at a time when the company's attempted concession from proprietary to open systems was deemed by some analysts as "too little and too late."
Wang Labs emerged from bankruptcy on September 20, 1993. As part of its bankruptcy reorganization, the company's iconic headquarters, Wang Towers in Lowell, was sold at auction. The complex, which originally cost $60 million to build and housed 4,500 workers in over a million square feet (100,000 m2) of office space, was sold in 1994, for $525,000. The renovated complex, which is now known as Cross Point, was subsequently sold in 1998, to a joint venture of Yale Properties and Blackstone Real Estate Advisors for a price reported to be over $100 million.
The company emerged from bankruptcy with $200 million in hand and embarked on a course of acquisition and self-reinvention, eschewing its former role as an innovative designer and manufacturer of computer and related systems. Later in the 1990s, and under the guidance of then CEO Joe Tucci, with the acquisition of the Olsy division of Olivetti the company changed its name to Wang Global. By then Wang had settled on "network services" as its chosen business.
The most advanced VS system, capable of supporting over 1,000 users – the VS18000 Model 950 – was released in 1999, and smaller models based on the same CPU chip were released in 2000 – the VS6760 and the VS6780. These were the last VS-based hardware systems.
In 1999, Wang Global, by then back up to $3.5 billion in annual revenues, was acquired by Getronics of The Netherlands, a $1.5 billion network services company active only in parts of Europe and Australia. Joe Tucci departed Wang after the acquisition. Wang Labs then became Getronics North America.
In 2005, Getronics announced New VS (VSGX), a product designed to seamlessly run the VS operating system and all VS software on Intel 80x86 and IBM POWER machines under Linux or Unix, using a hardware abstraction layer. The product was a joint commercial effort of Getronics and TransVirtual Systems, developer of the Wang VS virtualization technology that makes the New VS possible. VS software can be run under New VS without program or data conversion. The New VS is a combination of very specifically configured mainstream PC or PowerPC server hardware running virtualization software. It is interoperable with SCSI-based Wang VS tape and disk drives, which provide a means of restoring VS files from standard backup tapes or copying VS disk drives. Wang networking and clustering are supported over TCP/IP.
In 2007, Getronics operations worldwide were divided and sold to companies in respective local geographies. Dutch telecommunications operator KPN acquired Getronics in North America and some parts of Europe. In July 2008, Getronics North America (now an arm of KPN) announced the ending of support for the legacy VS line as existing contracts expired, and that TransVirtual Systems would be exclusive reseller of the New VS platform. Shortly after, in August 2008, KPN sold Getronics North America to CompuCom of Dallas, Texas.
The Wang VS product line, not actively marketed since the 1993 bankruptcy and a tiny portion of the Getronics business, survived in use into the 21st century; by 2006 about 1,000 to 2,000 systems remained in service worldwide. In 2014, CompuCom announced that all support for legacy VS systems would cease at the end of 2014, while support for New VS systems would continue through TransVirtual Systems.
