Minimal CP-M SBC design

On a tangent, I am curious: how difficult is it to make some form of
CP/M-68k work on a bare-bones 68000 or 68008 system?  Long ago, I did
wire up a 68008 system with leftover chips; but my memory is fuzzy.
Can't even remember if the DTACK grounded trick works on the 68008, or
if I forced access times somehow...

What does CP/M-68k expect in RAM, ROM and I/O locations?

Joe.
