While we were moving the CP panel off of the box to prime it (the box), the PS/2 cable got caught and ripped from the interface, leaving the connector still in it, and the cable on the floor. I won't go into detail on the expletives used, but they were bountiful.
"I'll just pick up another cable." Dumb.
Unfortunately, male-to-male PS/2 cables (PS/2 being a connection of the past anyway) are impossible to find in a store. Sure, they sell them online, but this thing is going to be finished by the weekend.
Thanks to Dave at work, who "lent" me 2 male-to-female PS/2 cables, I able to have at it with an old Weller soldering gun. Clip-clip go the female ends and strip-strip go the wires. Then strip-strip-strip-strip-strip-strip (x2) go the wires inside...PS/2 has 6 shielded connecting wires and 1 unshielded ground wire. Thankfully they were color-coded and matched up easily. Here was my set up.
Two battery clips to hold the two cables in place, and two clamps to hold the clips upright. I had a wet sponge to keep the gun tip clean. The first 4 or 5 went swimmingly, the solder melting like a champ, me breathing in all that glorious lead smoke.
Then, the gun decided to give out, and I resorted to soldering the that last two wires using my cigar lighter. Not the cleanest connections, but it worked! I electrical-taped everything together, and used the clamps (now zip ties) to keep any undue pressure or pulling away from the new connections.
Alex figured out what was wrong with Player 3 controls! It was just a break in one of the ground lines. One re-crimp and we were back in business! Now ALL the controls work, and we are happy.
