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

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]

Commands

The following list of commands are supported by Cromemco DOS.^[4]

Intrinsic commands

Later versions also support the ATTR command.^[10]^[11]

Extrinsic command programs

@ (Batch)
DUMP
EDIT
INIT (Initialize)
STAT (Disk Status)
WRTSYS (Write System)
XFER (Transfer)

Later versions also support the MEMTEST command.^[10]^[12]
