    1. The chip does not have synthesis parameters. The software does. The thing that makes HoustonTracker impressive is that the calculator does not have sound at all. The software generates ALL sound, rendering it on-the-fly, and then uses the link port for sound output by twiddling bits of (presumably) a register somewhere.

      1. The only output the TI calcs have is the TTL level link port. So it would be fairly lo-fi PWM, which can actually sound pretty good with some filtering.
