Run your CP/M programs direct on an IBM PC
MicroSolutions has released two different versions of UniDOS. On the one hand a pure software solution and on the other hand a plug-in card with a Zilog Z80 processor.
- UniDOS Z80 card
I am currently aware of two different (main) versions of the UniDOS program that can be found on the Internet:
- 1.11: no Z80 card necessary
- 1.27z: Z80 card absolutely necessary
I use the UniDOS version 1.11 on my 286 AT in combination with a CompatiCard I and UniForm. As described here, I could start Wordstar (V2.26) with UniDOS directly from an 8 inch floppy disk and work with it.
Running CP/M programs
If you are using UniForm-PC with a CP/M drive, you can start the CP/M *.COM program directly on the UniForm drive. If you have copied the CP/M programs to the hard disk, then you must rename the CP/M *.COM files as *.CPM. Afterwards you can start these files directly, like otherwise a *.COM file, see figure above.
Z80 coprocessor card
Following two pictures of the Z80 coprocessor card. These pictures are from the internet. I have no Z80 card, I am still searching ...
Documents and information
I don't know of any manuals. Nothing can be found on the Internet!?
