MDOS (short for Myarc Disk Operating System) – an operating system commercialized by Myarc. It was designed and implemented specifically for the Geneve 9640 by Paul Charlton. MDOS was designed to fully emulate the TI-99/4A computer while providing an advanced (for its time) virtual memory operating environment with full support for mouse, GUI, and complex mathematical applications.

The Geneve 9640 is an enhanced TI-99/4A clone. It was sold by the company Myarc as a card to fit into the Texas Instruments TI Peripheral Expansion System. Released in 1987, it is in many ways similar to the earlier TI-99/8, which was in prototype form in early 1983. The Geneve 9640 was designed by Paul Charlton, and the graphical swan on the boot up screen was designed by Mi-Kyung Kim.
