The PowerBook 500 series (codenamed Blackbird, which it shared with the older Macintosh IIfx) is a range of Apple Macintosh PowerBook portable computers first introduced by Apple Computer with the 540c model on May 16, 1994. It was the first to have stereo speakers and Ethernet networking built-in.
It was the first PowerBook series to use a Motorola 68LC040 CPU (simultaneous with Duo 280) and be upgradeable to the PowerPC architecture via a swap out CPU daughter card (with the PowerPC and 68040 upgrades for sale), use 9.5" Dual Scan passive color/B&W displays, 16bit stereo sound with stereo speakers, have an expansion bay, PC Card capability, two battery bays (and a ten-minute sleep/clock battery, which allowed for main batteries to be swapped out while in sleep mode), full size keyboard with F1-F12 function keys, be able to sleep while connected to an external monitor and have a battery contact cover included on the actual batteries. It included a single serial port which could be to connect to a serial printer or a network via Apple's LocalTalk. In another first, it also included an AAUI port for connecting to non-LocalTalk (usually Ethernet) networks.
The 500 series was discontinued completely with the introduction of the ill-fated PowerBook 5300. The PowerBook 190 was the de facto successor to the 500 and continued the only 68LC040 processor offering as the low-end of the PPC-based PowerBook family.
The 540c was rated #2 of the all-time best PowerBook models made according to Insanely Great Macintosh (survey taken Nov 2000).
The PowerBook 500 series was introduced on May 16, 1994 with the high-end active matrix LCD PowerBook 540c and 540, with the passive matrix 520c and 520 soon after. One of its marketing highlights was the promise of a PowerPC upgrade to its CPU and PC Card (PCMCIA) expansion. The introduction of this model came at the time of Apple's change over to the new PowerPC Chip from the 68k line of CPU's, and Apples advertising and promise of the PowerPC was the cause of headaches to the company. The strong demand for its ground breaking design and Apple's incorrect market prediction that customers would wait for the fully PowerPC PowerBook resulted in shortages early on.
In due course the 540 was dropped from the line, 8 mb of additional memory and the modem was offered installed from the factory, hard drive capacity was increased (from 160 and 240 to 320 and 500 mb), and the installed system upped from System 7.1.1 to 7.5. The PC Card Cage was also released, allowing Macintosh users to add PCMCIA capability to their laptops for the first time.
In 1995 Apple gave permission for Apple Japan to introduce an updated version, called the 550c, with a bigger display (10.4"), CPU with FPU (68040), bigger hard drive, and Japanese keyboard. It was only sold in Japan, and never received FCC certification.
With delays in the new PowerPC PowerBook 5300, demand for the PPC upgrade mounted, and Newer Technology began to market the upgrade before Apple did, although they had produced the upgrade modules for Apple first. What's more, they offered 117 MHz versions over Apple's 100 (actually, 99) MHz offering. Soon thereafter, Newer Technology introduced a 167 MHz model that outperformed the fastest PowerBook 5300, the $6800 5300ce, at a time when problems with that line became a real issue to Apple.
About the time Apple introduced the PowerBook 1400, Newer Technology introduced a 183 MHz upgrade with 128 Kb of L2 Cache that kept it ahead of the power curve performance wise. Newer Technology stated they could not produce more of the 183 MHz upgrades because the supply of connectors was exhausted.
Impact on the Industry
This laptop was the first in the industry to include:
- Trackpad instead of track ball
- 16bit stereo sound @ 44.1 kHz (Typical was 8bit mono @ 22 kHz);
- Stereo speakers (located in upper corners of screen);
- Ethernet via AAUI (A transceiver was used to connect to either UTP or Coaxial type wiring);
- Non specialized internal expansion bay for connecting many types of devices (PDS connector in left battery bay);
- "Intelligent" NiMH batteries (that is, had on-board circuitry to monitor health of battery);
- CPU on a daughter card.
And among Apple's PowerBook line the first to have:
- 68LC040 (with Duo 280), or 68040 (in Japanese model) CPU standard;
- PowerPC 603e CPU as an upgrade;
- 9.5" displays;
- 10.4" display (550c in Japan);
- Dual Scan passive color and B+W screens;
- CPU on daughtercard (first in any Mac) (PowerPC and 68040 upgrades);
- Expansion bay (PDS connector in left battery bay);
- PC Card capability (PCMCIA) via module;
- 2 battery bays (and a 10-minute sleep/clock battery);
- Full size keyboard with function keys (F1-F12);
- Sleep while connected to external monitor;
- Battery contact cover included on the batteries.
Variations across the range
Although the 500 "Blackbird" prototypes were black, only one of the five production models was completely black; that was the 550c, sold only in Japan. The 550c differed from the four two-tone grey models in a few other key respects as well, including a larger active-matrix color screen, a combined Roman/Kanji keyboard, and a full 68040 processor. The other models were all charcoal grey with darker grey trim, came with a variety of displays (active/passive matrix; color/greyscale), and used the 68LC040 processor (a low-cost variant without a math co-processor). The full-sized keyboard with 12 function keys, and used a 640x480 resolution display was consistent across the family.
Optional Internal Modem
The modem was developed with Global Village, and is a unique 2 part design. The transceiver with the modem connector is installed in the back, and the modem itself is located next to the CPU daughter card. It was a V.32 Terbo, and had a top rate of 19.2 kbit/s, but only with other V.32 Terbo modems as there was no official standard. Otherwise it would drop down to 14.4 kbit/s. Due to a bug with the new combined printer/modem port, the driver had to be upgraded to 2.5.5, and the Chooser was replaced in the GV install.
The 500 series of PowerBooks included the ability to use two batteries at the same time, allowing for 4 hours of battery life from two installed charged batteries. However the left battery also had an internal PDS slot that allowed for custom modules to be installed. Despite prototypes being made, only 2 devices reached the market.
PCMCIA "card cage"
One is the PCMCIA module. There were three versions; RevA, RevB and RevC. The RevC is the most useful as it can take 16bit WiFi cards, allowing the possibility to get a Powerbook 5xx connected online or in the home network using a technology that was developed after the Powerbook 5xx's were discontinued by Apple. The different revisions of the PCMCIA module were released by Apple to accommodate the developing PCMCIA standard. These modules are difficult to find, and the RevC module is in particular demand because it alone works with 16-bit WiFi cards.
PC Card (PCMCIA) cage, 16bit, 2 Type I/II or 1 Type III cards, using a 68000 CPU to convert the PC Card protocol to PDS.
The other is the FPU co-processor, to make up for the lack of one in the PowerBook's 68LC040 CPU. The FPU module uses a 68882 FPU co-processor made by Sonnet.
In total, almost 600,000 PowerBook 500 series units were produced, compared to only 300,000 PowerBook 5300 units.

At a time when most laptops had Grayscale displays, mono speakers with only 8 bit audio out, insufficient battery life, and some even had side mounted snap on track balls, the 500 series became the model for all laptops to this day. With the built in Ethernet (via a versatile AAUI transceiver), SCSI port (forerunner of today’s FireWire) and ADB (similar to USB), it had all the features of desktops at that time, making them the first viable desktop replacement laptops.
