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 (the same one used in the MSX2 family of home computers) 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 dif ...

Myarc Disk Operating System
MDOS (short for Myarc Disk Operating System) is an operating system commercialized by Myarc. It was designed and implemented specifically for the Geneve 9640 by Paul Charlton (technologist), 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. In 1993, Beery Miller the publisher of 9640 News, organized a group of Geneve 9640 owners and was able to purchase all rights to the source code for MDOS, Advanced Basic, the PSYSTEM runtime module, and the GPL Interpreter from Myarc and Paul Charlton. Over the years, MDOS has been updated by individuals including T. Tesch, Clint Pulley, Alan Beard, John Johnson, James Schroeder, Mike Maksimik, James Uzzell, Tony Knerr, Beery Miller, and others. Support adding SCSI, Integrated Drive Electronics, IDE, and larger ramdisks were added in the earlier years from the buyout. ...
