The Amstrad CPC 464 (short for Colour Personal Computer) was an 8-bit computer produced by Amstrad in the mid to late 80’s. It was designed to compete with the Commodore 64 and the Sinclair ZX Spectrum.
It used a CPU based on the Zilog Z80A CPU, with either 64KB (Standard) or 128KB of RAM.
The base unit integrated the computer itself, the keyboard and a built in cassette tape on the CPC464 or 3″ (not 3.5″) floppy disk on the CPC664.
The 3″ diskette used in Amstrad CPC664 and CPC6128 models, as well as the Amstrad PCW series of Wordprocessors.

The main units were only sold bundled with either a colour or monochrome monitor that doubles as the main unit’s power supply.
The machine featured a BASIC interpreter based on Locomotive Basic for the Z80 in ROM.
The range was superseded by the Amstrad CPC6128.
