IBM Terminal Keyboard Controller
« on: Sun, 19 June 2016, 10:32:23 »
Hello,

I recently ordered a cheap IBM Terminal Keyboard (1394312) off eBay and took it apart because it was very filthy. I took a look on the controller and saw 4 pairs of jumper pins of which one was shorted by a jumper. I attached a picture of the controller, so you can see it. Does anybody know what the different jumper pins do?

If its similar to the controller on my board they configure the ID code of the keyboard. Usually they are safe to ignore.

Thanks for your answer. I don't have any DIP switches on the bottom of my keyboard. Do you know what they do?

They provide the ID code to the keyboard.
