Following up on my earlier post, further adventures in Dolch cabling.
I found the crimp tool I remembered having, but it was only for RJ45 connectors, not the tiny RJ9 ones I needed. Being an impatient sort, I decided to go ahead and solder on the new cable I got from Nubbinator, instead of waiting for the right adapter (sound familiar?)
At first I tried soldering on the recycled RJ9 telephone handset connector I'd used to test the board, but I think the stranded wire was just too friable, I ended up breaking it when I tried to strip it for soldering. So I took apart the female RJ9 connector inside the case and used that to solder on the new longer PS2 cable.
The Dolch pinout linked earlier in the thread refers to a six-pin connector, but indicates the middle four wires map to the RJ9, so I started there.
Going by the Dolch pinout linked above, and a PS2 keyboard pinout (
http://pinouts.ru/Inputs/KeyboardPC6_pinout.shtml), I identified which wires in the PS2 cable needed to be soldered to the RJ9 wires.
Wires from the Dolch PCB (Left to Right in image):Black = Ground
Green = +5v
White = Data
Red = Clock
I soldered on the longer PS2 cable (ignore the crappy tape job, please!), and stripped back a couple of inches of the covering to make a thinner cable, as I didn't want to cut up the Dolch case.
Tested okay, using one of the new GeekHack store PS2-to-USB adapters, so I buttoned up the case. All of the case screws are under the rubber feet, and two of the feet were already missing, so I used some spare furniture bumpers to cover the screws.
Short list of things to do the next time:1. New case screws. The Phillips heads of the stock screws were filled with crusty rubber cement, and aren't in very good shape after a couple of rounds of taking off and replacing.
2. Replacement rubber feet pads. The ones I had on hand are decent, but I'd like to find some smaller diameter pads that will fit the stock case divots.
3. Heatshrink the PS2 cable. Tape works, but it looks half-assed.
