Geneve 9640

The Geneve 9640 is an enhanced TI-99/4A clone which was built by Myarc as a card to fit into the TI Peripheral Expansion System and used an IBM PC XT detached keyboard as well as a mouse. Released in 1987, it was in many ways similar to the earlier TI-99/8 which was in prototype form in early 1983. The Geneve, its custom ASIC chip, and the MDOS operating environment were designed by Paul Charlton
