Cromemco DOS orCDOS (an abbreviation forCromemco Disk Operating System) is aCP/M-like[1]operating system byCromemco[3] designed to allow users of Cromemcomicrocomputer systems to create and manipulate disk files using symbolic names.[4]

Overview

[edit]
Cromemco Z-2 CPU unit and terminal

CDOS was written inZilog Z80machine code. Due to the number of available programs available to run underDigital ResearchCP/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]

TheCromemco Z-2 had the ability to run Cromemco DOS.[1][6] Besides CP/M 2.2 andCromix, theCromemco System One can also run Cromemco DOS.[7] TheCromemco C-10personal computer, introduced in 1982, also ran CDOS.[8]

Anemulator for a Cromemco CDOS system exists.[9]

Commands

[edit]

The following list ofcommands are supported by Cromemco DOS.[4]
