Best DOS for each model

CP/M-68k Hard disk driver, anyone?

The beauty of that is that you've already written the core of it, since the 16's Z80 has to do all I/O. The 68000 has no way of directly controlling any of the hardware; the Z80 must do it all. So a hard disk driver for CP/M 68K on the 16 would actually be Z80 code, with an interfacing shared-memory shim between the 68K and the Z80.

Actually since CP/M-68K runs on top of Z80 CP/M there may be almost no work to do.

I have a strange fondness for the radio shack computers. What DOS does everyone prefer for each model?

From the systems I ran back in the day:

Model III - NewDOS80
Model 4 - Montezuma Micro CP/M 2.2
Model 6000 - Xenix 3.2

I rarely ran anything but CP/M on my Model 4. It's still my goto OS on that machine.
