I am restoring an ibm model F keyboard and I do not know how to connect the motherboard pins with teensy 2.0. There is some scheme The keyboard output is 15-pin or game port

Hello mpereiro,

what kind of IBM Model F is that exactly you have? Is there a sticker on the back? That connector looks like the one on my bigfoot. Show us a picture of the keyboard if you're not sure.

I think it's a bigfoot.

Wow that's dirty.

Can't find the exact pinout, but I know I have seen the board pinouts for where the connector goes into the controller board. Regardless of connector, you have ground, data, +5 and clock pins on that connector on the inside. If you want the easy route, remove the old cable, put in a USB and hook up the Teensy inside, soldiering the pads to the board-end of the original cable.

Someone have the pinout?

Yeah, going to be doing just this for a Model M.

If you have a meter, you can do a continuity test for the individual pins on the original cable to clock, ground, 5v and data and build a box for the connector end (if you want to keep it 100% stock). But that requires a meter. And receiving connector. And a box to put all the jazz in. And that all assumes the cable is in good enough shape.

If you use our search function you will find more information useful to you.

The cable is perfect and gives continuity. With the pin board I think I solve my problem. I wanted to keep the keyboard intact so I would build an external box for the usb.

Thank you very much for the help

Great, show us some pictures when you are done!

I love Model F restoration threads. Keep us updated!

Great thread. I am restoring and modding one of these Bigfoots as well. The arduino info is definitely useful.
