I see you found my recording on soundcloud! That was truly an amazing instrument. The prototype at the UofA had the TI-9900 chip in it, of that I am certain. At the time, it was the biggest chip I had ever seen in my life (64 pins). Whether that made it a late 8-bit version or an early 12-bit version I don't know. Nice to see the Coupland getting a little press. I got so tired of refuting the "vaporware" label - nice to have a published source to send people to.
