There was an awesome c64 music radio show on KDVS (the UC Davis radio station) back in the nineties, but I can find zero record of it existing. Does anyone on this thread know anything about it, or even perhaps have recordings?
But note:

> No; it's relatively slow. The MOnSter 6502 runs at about 1/20th the speed of the original, thanks to the much larger capacitance of the design. The maximum reliable clock rate is around 50 kHz. The primary limit to the clock speed is the gate capacitance of the MOSFETs that we are using, which is much larger than the capacitance of the MOSFETs on an original 6502 die.
So if you built a SID using the same techniques and components, you couldn't run it in real-time without the pitch being way too low or without modifying the design. I'm not sure how hard this would be to avoid with better-spec'd components, but intuitively it makes sense for a much larger circuit to run much slower.
