Using the magic of the Teensy, I was able to bring back 4 New old stock IBM Model F Bigfoot keyboards,

The software here made it very easy, and I used the firmware created just for this from Geekhack, I'll be buying more in the future to do this again.

Here is an album of me doing this: https://imgur.com/a/DL40jO6

Thanks again for the wonderful product!
