6502
From CPCWiki - THE Amstrad CPC encyclopedia!
Originally the CPC should have been designed around the 6502 processor. A prototype was designed, also know as the gray Amstrad, because of its gray casing!
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.
