I found a couple useful links related to USB keyboard adapting...

The first, is the design for a TI-99/4a load interrupt switch. This is significant, as my TI USB Keys project has some open GPIO pins, one of which can could be mapped to load interrupt.

The second is Arduino code to output XT keyboard codes. My same board for connecting to the TI, substituting an XT pigtail should be able to interface the Geneve 9640 if I mashup my software and Kesrut's software. The end goal being my TI and Geneve share a keyboard and VGA display.
