This target is under development

There is a very little downloadable software for this machine. In theory it can run both CP/M and S-OS and hence applications compiled for either OS will work. However we've been unable to find versions of either OS that can be used on this machine. As such usage under those targets is complete untested.

As a result the machine has been tested under the +pasiopia7 target.

zcc +pasopia7 app.c -create-app

A .dsk file will be created that can be inserted into an emulator and will auto boot.

The system runs in all RAM mode, meaning that a full 64k is available to your application. This operational mode causes problems with the Takeda emulator and the reset menu option doesn't work as expected.


The target has been tested using the Takeda emulator. The Mame emulator implementation is incomplete and does not support floppy discs.

Graphics support

The following screen modes are available:

  • Mode 0: 40x25, 40x25 lores graphics
  • Mode 1: 80x25, 80x25 lores graphics

The machine does support hires graphics, but it is not currently supported by z88dk.
