I rather suspect a 16F84 will choke on something that complex. You won't be able to use interrupts to deal with the wheel encoders, because the 16F84 only has one external interrupt line. Are you using digital gyros, or analog ones with a pile of serial ADCs?
as i have it now, there are 3 protoboards, 2 wirewraps and a white breadboard with 2 pic 16f84's (one intrupts per) and a basic stamp 2. its tearably iniffecent, and can only be polled about twice a second.

i am extrealy eager to learn how to do anything else, but im stuck here with a bunch of mechanic-style guys and a zero tollerence electronics budget. at home i have a MEL "Epic" programer and the Pic Basic Pro software... http://www.melabs.com/ any advice on better pics would be GREAT. 16f628 i will look into tonight. much thanks...
