single-sided copper-clad board? Used the drill bits for the holes or to remove the copper? Or did you photo-etch the board?

(curious, I'd really like to do prototype circuit work, but it's a major PITA).

single-sided copper board, photo-etched (since I didn't know about the modern toner-transfer stuff that everybody uses these days instead), hand-drilled with a push drill.

The cat-5 cable is for the signals from the main cpu board - q, clk, DC power, and AC power.

The drilling is really the biggest PITA. Makes me wish I had a drill press. The etching is the easy bit.

I get most of the random parts and raw PCBs from Halted in Sunnyvale; most of the IC components come from Digi-Key or Mouser.

The photo-etching from Halted as well? (been there many times, used to work about 3 blocks from there).

The photo-etching was because I didn't know any better - check out http://www.fullnet.com/u/tomg/gooteepc.htm for a far, far easier method. (Halted does have pre-sensitized PCBs if you insist on photoetching, though.)
