With these operating system options, users can choose from a vast range of application software to meet their processing needs.

A comprehensive set of programming languages is also provided, for users who want to develop their own applications:

  • Pascal
  • C Language
  • Assembler

The flexibility of the system's software is matched by its hardware. Memory capacity starts at 128K bytes and can be expanded to 640K bytes. In terms of external storage, the system offers a variety of options:

  • 320/360K byte diskette(s)

The system supports an integrated 9" monochrome video, this video provides advanced graphics features with a maximum resolution of 640 x 400 pixels. If a larger screen is required, or colour output is wanted, either of the M24's 12" videos can be connected.

The keyboard is a compact, industry-standard 83-key input device. During transit the keyboard is attached to the front of the basic module, thus protecting the video.'
