Revision as of 08:47, 1 April 2008
Microprocessor from Zilog, wich is used in the Amstrad CPC Computers. The Z80/Z80A was a very popular microprocessor, used in a great variety of home computers and appliances as far-fetched as satelites. It was even used in the Commodore C128 as a secondary processor in order to achieve CP/M compatibility.
