I saw a CDTV in action once, does that count?
CDTV's were pretty sharp looking machines back then and looked a lot like modern DVD players. Again, C= well ahead of it's time and nothing to show for it. :-(
Well, get your hands on the hardware reference guide RKM. If you can find source code for older games or demos you'll see how they killed the OS and banged the hw. Good luck!
