If you can find a Hauppauge 4860, you get an i486 and an i860. Toss in a DAC960E EISA Raid controller and you get an i960. And an NE3200 EISA network card, and get an i80186. Add a National Instruments AT-DSP2200 EISA data acquisition card, and you get an AT&T DSP32C. Add a A Hercules Graphics Station card and get a ti34010. Add an Opus card or two and get more (mc88100? SPARC?). That's 8 processors, 6 of which are directly available for fiddling. I've had, at one time or another, all these cards, but since I never put them together, I guess I don't win.
