I think this is puny enough that it can't even do any mutlitasking at all. CP/M may run on it, but stuff at this level is generally programmed from a basic port of a kernel up to the user interface on a device per device basis.
Just my impresssion. Doesn't mean anything realy.
What does it currently run as a OS?
