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]
