While I was investigating, the exhibitor (MillipedeMan aka Mark), told me the machines were frustrating to use, as TI only supported one communications method on the unit, a proprietary protocol called HexBus, and produced very low quantities of very few peripherals that work on the bus. Most frustratingly, they never producing a mass storage device in any appreciable quantity, and there was no other way to save programs written on the unit.

Wow! Many years ago I bought a CC-40 on ebay for pennies, boxed NOS. I forgot about it for over a decade and found it again recently looking for other things, this could be an excuse to get it out and see if it still works :)
