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. The graphical swan on the boot up screen was designed by Mi-Kyung Kim.

The unit included a faster processor (12MHz [http://www.chipdocs.com/datasheets/datasheet-pdf/Texas-Instruments/TMS9995.html TMS9995] ), enhanced graphics with 80 column text mode (via the Yamaha V9938 video display processor), 16 bit wide RAM, MDOS, and was compatible with nearly all TI software and slot-mounted hardware (an adapter was available to allow the sidecar-only Speech Synthesizer to be installed inside the Peripheral Expansion System). A toggle switch was mounted to the side of the PEB to allow insertion of wait states to bring the computer down to the same speed as the original console, allowing compatibility for games and other timing-critical software.
