Hey John! The only chips I am looking for are the salted variety
I want them to run Turbosynth! I don't know if you are familiar with it? I only learnt about it a few months back after finding a G4 'soundflower' iMac in my parents shed and investigating uses for it. It is one of Apple's greatest design achievements if you ask me, right down to the included speakers and the dual boot OS 9.22/OSX 10.1 operating system that it came standard with.
I have been running Turbosynth 2.21 on it just fine under OS9 using the built in soundcard, but running it on a compatible DSP based protools system allows a bunch of extra processing to occur in real time and also adds a few extra processing modules to it - like a diffuser. Having an interface with some kind of digital I/O on it, even if it is just a 888 or something similar would speed up the workflow as well.
Actual documentation seems little thin about exactly what DSP hardware it needs to run, but I am pretty sure a Sound Accelerator II or Audiomedia II card will cover the DSP aspects, and a Samplecell card will add a bunch of midi functionality to it.
