Odd Cromemco system:
I've never seen this machine before. I had no idea Cromemco was into Unix.
Nothing odd about it; they'd had Cromix, a sort-of-UNIX available on their
Z80 and 68000 systems since around 1980, but by the mid-80s they finally
cried uncle and made UNIX systems available with the x20 series, essentially
the same S-100 boxes as the older ones, i.e. a 120 was essentially an
upgraded System 1, a 220 an upgraded CS-2 (Z-2) and the 320 was the
System 3 (8" FD), all with slightly changed styling, a 68010 or 68020 with a
68881, minimum 2MB, minimum 9 ports and an external DC600 tape drive.
They also brought out a new CS-400/420 tower version with the tape drive built in.
The x00 series were essentially the same systems but running Cromix, although
since they were S-100 systems you could put whatever cards you wanted into
them and run whatever you wanted, even CP/M or CDOS (their CP/M clone),
although with the later CPU boards without a Z80 those programs ran on the
Z80 in the I/O processor.
I believe there was also a 4000 Mammoth running parallel 68030s on the VME
bus, although I don't have one and have never even seen one.
I've got two of the 420s sitting on my verandah gathering snow; wonder what
the cold'll do to the infamous rollers in the tape drives...
I could dig out some old price lists if anyone's interested in the available models.
