That's cheating, of course. I don't remember if PETs could be coerced into it,
but C64s can run CP/M 2.2 just fine with an add-on Z80 cartridge. They just
can't read the MFM disks, but neither can the Apple CP/M IIRC. There's
nothing about having a sidecar intelligent peripheral that's per se limiting
about what choices you have for an OS. Besides, if you really wanted a custom
DOS on a Commodore drive, you can either load the DOS into drive RAM and have
it execute there, or make the drive just a serial slave and feed data to the
Commodore for processing. Most custom Commodore formats did the former.
