Perhaps I will try to get ahold of CP/M for it.
There are multiple different ports of CP/M. For the model 4, RS sold
"CP/M+" (3.0), but some of the folks that ported CP/M to the 3 (such
as Montezuma Micro) also had releases of CP/M 2.x
For the model 2, there were several implementations, including "Lifeboat"
and "Pickles and Trout"
