Cromemco DOS or CDOS (an abbreviation for Cromemco Disk Operating System) is a CP/M-like[1] operating system by Cromemco[3] designed to allow users of Cromemco microcomputer systems to create and manipulate disk files using symbolic names.[4]
Overview
[edit]![](http://178.128.105.246/content-http-upload.wikimedia.org/wikipedia/commons/thumb/6/68/Cromemco_Z-2_Computer.jpg/220px-Cromemco_Z-2_Computer.jpg)
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.[5]
The Cromemco Z-2 had the ability to run Cromemco DOS.[1][6] Besides CP/M 2.2 and Cromix, the Cromemco System One can also run Cromemco DOS.[7] The Cromemco C-10 personal computer, introduced in 1982, also ran CDOS.[8]
An emulator for a Cromemco CDOS system exists.[9]
