In April 1985, the CPC464 was replaced by the CPC664. This was basically the same machine, but with a slightly improved keyboard and a 3" disc drive in place of the cassette recorder.

Along with the disc drive, Amstrad also bundled a copy of the CP/M operating system, to give access to a number of business applications.
