Actually, CP/M bears *very* 
little resemblence to or 
influence from Unix -- the 
early, pre-VMS proprietary 
DEC OSs like TOPS were much 
more of a factor in CP/M's 
design.

CP/M *always* supported 
floppy drives, from the very 
first release for the Intel 
MDS system.  The modularity 
that made it so easily 
adaptable to a variety of 
hardware within the 
8080/8085/Z80 CPU families 
came later on, with version 
2.x.

No offense, but what the
