In many ways it is very similar to F1 in single chip mode only faster with more memory. And 2 chips cost the same from digikey as the PLCC to DIP adapter. The only glue logic required to get it running is a crystal or ceramic resonator. If that is too expensive then a resistor and capacitor will also work for the clock. Programing is in circuit via the ICE. In fact the demo board that comes with the ICE has enough proto area to accomplish most of what people want with the second circuit board.
Of course I still can't figure out how you were going to build a minimal x86 board for < $100 and still have enough money to interface it to the rest of your system. Especially not with digikey prices.

Yow! Those PICs must have come a long way since I last looked at them. The 16F84 was the last PIC I used, so perhaps I shouldn't have been so quick to dismiss them. Oh well, I'm happy with what I have now, and that's what matters. I'll definately take a closer look at them for the next board! (Is your team sponsored by Microchip? They wouldn't happen to have any neat-o toys to give to us to, uh, sway us their way, would they?
)
Eh? You don't think I can make a x86 board for <= $100 (DigiKey)? I'm thinking I accept that challange as soon as the 6 weeks ends!
