FYI, Cromix v11 _DOES_ run on a Z80.  I worked for the local Cromemco store
here and we had it back then.  As a matter of fact, I was at the VPs house
last night and he was busy connecting it via modem to his PC clone.  Whipping
up his own quick and dirty XMODEM transmitter in C to Procomm 2.4.2.

Cromix/Z80 uses bank swapping--the first 64K is for the OS, other 64K banks
are used for CP/M & CDOS tasks.  REAL Cromix tasks can share a single 64K
bank if they are relocatable-binary.  The C compiler he has for it is pitiful..
Slow as xmas, but it works!!  Three pass from C to ASM, then to OBJ (?) then
a link to .BIN (whew!  usoft/borland runs a little faster now-a-days! :-) )

Cromix v20 and up used a Z80 AND a 68000 processor; it could figure out what
you were trying to run and select the correct processor.

If anybody has any Cromemco stuff they'd like to sell (or buy!) drop me a
line and I'll have Steve get in touch w/you.

PS - somebody ported Cromix to an AMIGA??? Hell, that'd almost be worth having!
