True, it may not be feasible to build a high-performance computer based on current generation x86 chips, but there are so many alternatives: some of the 8-bit favourites are still being made (6502, z80); then there's the AVR, PIC, TI 430, the Propeller, various ARM chips. There are free or low-cost CAD packages, and having small series of PCBs made is almost ridiculously cheap. You can get logic analyzers for $150 or so, and if you want to experiment with FPGAs, you can get useful development systems for well below $100.
