Well, that was the plan :)
Mabey adding some wavetable stuff in there for fun...

well, the reply i got from Kensington wasn't that helpful.
(it appears that kensington bought out Gravis)

I think i will look at my two ultrasounds and see if i can reverse
engineer the decoder logic and check if the memory map is contiguous.

If it is, then it shouldn't be too dificult (finger crossed)

Does anyone have any surgestions for how to do this?? (other than circuit
tracing)

Cheers,
Alwyn
