The Amstrad CPC 664 was sold for only one year. Successor to the Amstrad CPC 464, it was quickly replaced by the Amstrad CPC 6128. It was sold with a monochrome green or colour monitor and a built-in floppy disk drive. The floppy disk format was the Hitachi 3 inch, an uncommon format already used on the Tatung Einstein and the Oric Atmos.
Like the CPC 464, its price was very low, which explains why about 10,000 units were sold in less than a year.
The Locomotive Basic interpreter was the same as the CPC-464, but had some extra commands like FILL to fill a graphics area, FRAME to produce smoother graphics, and MASK to draw a series of dots. The editor was also slightly improved.
The 664 was delivered with the AMSDOS and CP/M 2.2 operating systems. The LOGO language was supplied with the CP/M disc.
