  Hi Andrew,

 Just sitting here wondering why you're not using one of the enhanced-
 functioning Z80 chips.  Even going with the 64180 or Z180 would give 
 you 2 UARTS and an MMU, in addtion to 2 DMA channels and a timer.   
I can't speak for Andrew, but for me, I already have this SBC with
CPU, some RAM, enough ROM, and a peripheral bus with 5 or 6 PIO
chips, all in a package a little smaller than an Apple II PSU.

You might ask on comp.os.cpm; at least one person there claims to have
installed CP/M on a printer buffer/sharer.
