CODOS (Channel Oriented Disk Operating System) is the name of the Disk Operating System made by MTU for KIM-1, SYM-1 and AIM-65.
The DOS needs the K-1013 floppy disk controller, 8 inch disk drive(s) and optional the K-1008 Visible Memory.

CODOS V2 was the version for the MT-130/140. Lots of software is available, see the MT-130 page for manuals.

CODOS V1 is being reverse engineered from CODOS V2 by Eduardo Casino.
