Randy Wigginton was one of Apple Computer's first employees (#6), creator of MacWrite, Full Impact, and numerous other Mac applications. He used to work in development at eBay, Quigo, Inc and Move.com. In Nov 2010 he left his position as a "Site Reliability Engineer" at Google Inc., purportedly after leaking news of a $1,000 holiday cash bonus to employees. He has a daughter named Andrea and a son named Ken.
Wigginton was a student at Bellarmine College Preparatory in San Jose, California, interested in computers just as the earliest microprocessor-based computers were being assembled by hobbyists. He had heard about the Homebrew Computer Club but had no way to get there until he started getting rides with another club member, Steve Wozniak. The two hit it off, and Wigginton became one of Apple's earliest employees in 1976, and was present with Woz when the Apple I was first presented to the world at a Club meeting.
Wigginton collaborated with Wozniak on the circuit design and ROM software for the Apple II in 1977. As Woz wired up color graphics circuitry, Wigginton wrote machine language graphics subroutines, and Chris Espinosa, another high school student, wrote demo programs in BASIC. Wigginton wrote several early programs for the Apple II, including a checkbook-balancing program co-authored with Apple's vice-president of Marketing Mike Markkula. Wigginton was one of the Apple employees who adapted Microsoft's 6502 BASIC for the Apple II; it was dubbed Applesoft BASIC. He was responsible for the floating-point math routines. The Applesoft BASIC Reference Manual includes a section entitled "Rounding can be Curious", in which it is documented that the ROUND function, which rounds a number to a prescribed accuracy, is not monotonic: in other words, for some x and y, such that x<y, ROUND(x)> ROUND(y). (The problematic ROUND function does not appear in Applesoft II, the version that most Apple II users are familiar with.)
Perhaps his most critical early contribution was the RWTS (read/write track-sector) routines for the Disk II, the 51⁄4" floppy disk controller introduced at the Consumer Electronics Show (CES) show in early 1978. Wigginton and Wozniak wrote the final version of the software in Wozniak's hotel room on the eve of the show.
In 1979 Apple's President Mike Scott enlisted Wigginton to write a secret competitor to VisiCalc, to use as leverage against VisiCorp (then Personal Software, Inc.). To keep the project under wraps, it was given the code name Mystery House.
Wigginton was a member of the original Apple Macintosh design team. Wigginton left Apple in September 1981 and formed Encore to work on his own. However he was quickly contracted by Apple to help work on MacWrite on a semi-formal basis. When the Macintosh shipped in 1984 he again turned to his own projects, starting a new spreadsheet program that would eventually be released, after four difficult years, as a product named Full Impact.
