Cromemco DOS (CDOS or Cromemco Disk Operating System) – a CP/M-like operating system by Cromemco, and written in Zilog Z80 machine code. The Cromenco company was started in 1975 by two Stanford University grad students, Roger Melen and Harry Garland.

Early products were cards for the S-100 bus, as used by the Altair and IMSAI computers.

These computers were built around the S100 bus. The S100 BUS was a standard (also known under the name IEEE 696) for connection on Zilog Z80 or Intel 8080 processors. A lot of S100 cards were available for the Cromenco systems.

Cromenco systems :
– System 0: Z80 A + RAM 64 KB + 2 floppy disk drives (390 KB each),
– System I: As system 0 + 1 hard disk (5 MB).
– System III: Z80 CPU, Dual 8″ Persci electrically driven floppy drives, 64 KB RAM. It was S-100 bus, Multiuser, used MP/M operating system.

In 1982, Cromemco also introduced the CS-1H system using a dual processor board (Motorola 68000 and Z80) and offering 16 MB of address space.
