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]
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
[edit]The following list of commands are supported by Cromemco DOS.[4]
Intrinsic commands
[edit]Later versions also support the ATTR command.[10][11]
Extrinsic command programs
[edit]- @ (Batch)
- DUMP
- EDIT
- INIT (Initialize)
- STAT (Disk Status)
- WRTSYS (Write System)
