The MOS Technology 6502 is an 8-bit microprocessor designed by Chuck Peddle for MOS Technology in 1975. When it was introduced it was the least expensive full featured CPU on the market by far, at about 1/6th the price, or less, of competing designs from larger companies such as Motorola and Intel. It was nevertheless faster than most of them, and, along with the Zilog Z80, sparked off a series of computer projects that would eventually result in the home computer revolution of the 1980s. The 6502 design was originally second-sourced by Rockwell and Synertek and later licensed to a number of companies; it is still made for embedded systems.
The 6502 was used, among others, for Commodore's 8-bit machines.
Originally the CPC was destined to be designed around the 6502 processor. But when Amstrad approached Locomotive_Software to develop a Basic for it with a very tight deadline, Locomotive PLC, who already had a Z80 Basic in the works, urged and convinced Amstrad to switch to the Z80.
A prototype was designed, also know as the gray Amstrad, because of its gray casing! note: this is probably wrong. The gray CPC depicted below is probably an early development prototype handed out to a software house.
The Gate Array was a single print on top of the actual motherboard.
Even the prototype had had the small, and for some anoying, computer/tape diagram.
Please add more info here.....
