Perhaps I should have been clearer that I meant "other examples of
CP/M 3.0 Plus for the Commodore 128"... there are several images on  I am looking for versions not posted there so I can
figure out what versions work and which do not.

Having tracked down some links, it looks like some other brand of
machine, not quite what I was looking for.

To be clearer, I'm not trying to evaluate "CPM 3.0 Plus" on all
platforms, just on the C-128.

Thanks for the offer, but I don't think it's going to help me solve my quandry.

I'm not aware of it being emulated - there's a real Z80 in the C-128
(and the C-64 CP/M cartridge), but what is "odd" is that the native
Commodore CPU participates in some of the I/O.  They did not write IEC
routines in Z-80 code as far as I can tell, and there is an underlying
"6502 BIOS" that's part of Commodore CP/M.
