Trying to create my own AT to PS/2 adapter but having a major problem...
« on: Fri, 06 December 2013, 17:37:20 »
The colors of the internal wires don't match up.  :mad:

The PS/2 is of course Red, Greed, Yellow, and White but the AT connector is Red, Brown, Orange, and Black.

I basically want to create a extended AT to PS/2 adapter so I took the 6-inch or so adapter that I already had and cut it in half with the intent on splicing it with a salvaged PS/2 cable from an old keyboard. Well it would seem the adapter doesn't adhere to standard colors.

I've looked up pinouts but those don't really tell me jack squat as all they are are what the actual pins are...not which pin corresponds to what colored wire (I mean really, what's the point?).

So yeah any help is appreciated...the sooner the better!

Here you go. Hopefully you have a continuity tester, so that you can touch wires to see what it connected to what.

You can easily make a ghetto tester if you have a flashlight with a removable bulb, a battery, and a piece of wire, but it is easier if you have 3 or more hands.

“Any split that is higher than 5%,” the letter states, “will be seen favorably by the RNC and President Trump's campaign and is routinely reported to the highest levels of leadership within both organizations.”"

Alright...I just ended up completely destroying the original PS/2 end of the adapter to see exactly what wires went to what pins...got it working! Feel like I really accomplished something! :D
