Cromemco DOS or CDOS (an abbreviation for Cromemco Disk Operating System) is a CP/M-like operating system by Cromemco designed to allow users of Cromemco microcomputer systems to create and manipulate disk files using symbolic names.

Overview

CDOS was written in Zilog Z80 machine code. Due to the number of available programs available to run under Digital Research CP/M at that time, CDOS was designed to be upwards CP/M-compatible. Many programs written for CP/M versions up to and including version 1.33 run without modification under CDOS. However, programs written for CDOS generally do not run under CP/M.

The Cromemco Z-2 had the ability to run Cromemco DOS. Besides CP/M 2.2 and Cromix, the Cromemco System One can also run Cromemco DOS. The Cromemco C-10 personal computer, introduced in 1982, also ran CDOS.

An emulator for a Cromemco CDOS system exists.
