Geneve 9640


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.

Hardware

The Geneve 9640 features a 16-bit TMS9995 processor clocked at 12 MHz. A Yamaha V9938 video display processor provides 256 color graphics at a 256 x 424 resolution, 16 color graphics at a 512 x 424 resolution, and an 80 column text mode. Audio is produced via an SN76496 programmable sound generator, capable of producing three simultaneous square waves at sixteen different volume levels, as well as an additional noise channel that could produce either periodic or white noise in three different frequencies and at sixteen different volumes. An IBM PC XT compatible detached keyboard and a mouse are used for input. The Geneve 9640 is compatible with nearly all software written for the TI-99/4A. An adapter was made by a company named Rave to allow the sidecar-only Speech Synthesizer to be installed inside the Peripheral Expansion System.
