			== The 'Version 0' Prototype ==

			The 'Version 0' motherboard prototype was the motherboard originally designed for the MOS 6502 microprocessor.
			That board is owned by Roland Perry, the Amstrad CPC 464 project manager by 1983.
			The board was shown by Roland in Retroalacant 2023, Alicante (Spain).

	The [[Gate Array]] was the only component of the Amstrad CPC, which was not a standard one but developed by Amstrad. Before it could be produced as a single chip, they had to make tests with a prototype, which was a single print on top of the actual motherboard.		The [[Gate Array]] was the only component of the Amstrad CPC, which was not a standard one but developed by Amstrad. Before it could be produced as a single chip, they had to make tests with a prototype, which was a single print on top of the actual motherboard. Aside from the Gate Array logic, the PCB does also contain the 32K BIOS ROM (stored in four 8K EPROMs).

	The first cases of the [[CPC]] 464 had a grey colour instead of the later used black colour. Probably these prototypes have been sent to several software houses to enable them to start developing CPC software before the computers' release.
