>As for being scientifically correct, Commodore was infamous for cutting corners so resistances (and prob other parts of fabrication) varied wildly so at best you can probably compare to specific chips (even if families of fabrication are closer,esp w.r.t to 8580 vs 6581 behaviours). It would be really neat if Chipsynth were capable of emulating those different resistances, to tweak them a bit to get a 'warmer' sound or something different, to allow further tweaking of the sound. I'm not sure if Chipsynth is emulating at the silicon gate level, or the analog circuits within the SID. Would be cool if it were.
