The 2000 isn't fully compatible either i thought since its one of the few PCs using the 80186 processor. When i acquired mine (also without a monitor and i think without keyboard or software ) i sort of accepted id likely not get it running. But perhaps the software is out there and less of a concern than i thought.
I didn't know it was compatible with the cm-1 but i never checked what video card mine had. Still an interesting system historically.
