Geez, you're a helpful one, aren't you?
Okay, revised list (I'll just order from allelectronics once I have confirmation I'm good ... Rat Shack here is teh sux):
SPST N.O. MOMENTARY PUSHBUTTON
5 VDC 1 AMP SWITCHING POWER SUPPLY
10 OHM 1/4 WATT
112 OHM 3 WATT SAND
10K LINEAR PC MOUNT POT
500 OHM SQ. TRIM POT
0.1UF DIP CAPACITOR
36 PIN FEMALE CONNECTOR, PC MOUNT
RJ-45 CORD COUPLER, STRAIGHT THROUGH FOR DATA
6' CABLE WITH RJ-45 CONNECTORS
GMA FUSE HOLDER, PC MOUNT
1/2 AMP 3AG FUSE
SOLDERABLE PERF BOARD
Think that'll do the trick? I assume I'll use the same pinout on the centronix connector, just moving the other end to the appropriate pin, and that this allows me to use a printer cable, right?
edit: thinking 16 gauge wire throughout ... the wire just slides into the holes of the centronix conn, right?
