Amstrad DDI-1 manual Amstrad

Two operating systems are supplied:

AMSDOS is an extension of the cassette filing system in CPC464 BASIC, and allows access to the BASIC interpreter.

CP/M 2.2 is the standard 'random access' Z80 disc operating system for over 5000 commercial programs - ranging from business and accounts software to second languages and scientific and engineering analysis. Thanks to the thoughtful implementation of CP/M on the CPC464, CP/M files may be freely mixed on the disc with AMSDOS files, which are automatically labelled with the appropriate filetype.

Digital Research's famous Dr LOGO has emerged as the most universal educational and teaching medium - combining the unique user-friendliness of 'turtle graphics' with sophisticated processing power. Dr LOGO is acclaimed as the most comprehensive implementation of LOGO available and is supplied free as part of your Amstrad DDI-1 package.
