Fifty years ago today, on September 16, 1975, MOS Technology exhibited the 6502 at WESCON, making samples available:
> Here the story takes one of those legendary turns. Steve Wozniak had been designing the Apple I around the Motorola 6800, but he sees the MOS Technology ad, realizes he can get a better price (even better than a Motorola discount he can take advantage of as a Hewlett-Packard employee), goes to WESCON, and buys a couple of chips from Peddle, who’s selling them in a jar from a suite in a nearby hotel because WESCON won’t let them sell product at the convention. The 6502 is soon in the Apple I design. Only two hundred Apple I computers were manufactured in 1976, but by that time, Wozniak is already thinking about the Apple II, introduced in 1977, which will quickly take off like a rocket, starting the use of the 6502 in the personal computer industry with a bang.
I wrote my first chess-playing program in 6502 hex because I didn't have an assembler, and I still remember some of its opcode values all of these years later. Such a fun little chip!
I much prefer Chuck Peddle's telling of the story of surrounding MOS's acquisition by Commodore and the history of the 6502 at VCF East: https://www.youtube.com/watch?v=PBnmJhEOdC8
The 6502 is as important, if not more, than the iPhone. Simplicity, elegance that powered the early days of the personal computing revolution.
By the way, this is a terrific article.
