The Amstrad CPC 464 was an 8-bit home computer produced by Amstrad in the 1980s. 'CPC' was an acronym for 'Colour Personal Computer', although it was possible to purchase a CPC with a green screen[?] as well as with a colour screen. The CPC 464 was designed to be a direct competitor to the Commodore 64 and ZX Spectrum systems.
The CPC 464 featured a Zilog Z80 processor, 64K of RAM, a palette of 27 colours, and a tape player to store programs and data. Like many home computers at the time, the 464 had a version of the BASIC programming language in ROM (the implementation was Locomotive Basic version 1.0). Because the CPC 464 shared a processor with the ZX Spectrum, some games manufacturers developed games for the two systems partly in parallel.
Note about the model names:
The first digit was a code for the main storage system; '4' denoted a tape deck and '6' a 3 inch floppy disk drive. The remaining digits described the RAM capacity. Thus:
Some later models had extra functions built into BASIC, an enhanced colour palette and a read-only cartridge system. This 'Plus' range also included the GX4000 console, and was a massive commercial failure, not least due to limited game releases from other companies. The plus range was only available for the CPC 464 and CPC 6128 models and was denoted by a '+' following the model name.
Magazines available for the system (at various times) included Amtix, Computing With The Amstrad, (the official) Amstrad Computer User, Amstrad Action, and CPC Attack!
