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.....
