Help Troubleshooting a Broken Keyboard

[THATGUY69]

Hello, I recently picked up a package deal on craigslist(Model F At, Tandy Enhanced 101, and a NTC board with white alps) for $65 usd. The Model F is worth the price of the deal alone, but I curious about the Tandy board. The keyboard appears to be dead, with no lights or anything working when plugged into a computer. The computer doesn't recognize it at all. I know this board probably isn't worth going through the hassle of fixing, if possible, but I'd still like to give it a try. I took apart the board and I didn't see any burn marks or blown out capacitors on the controller. The cable also does not have any problems with it and when using a multimeter, the board is getting power past the cable. If you have any suggestions about what to do next, I would definitely appreciate it.
Thanks!

I am pretty sure that Tandy used a proprietary protocol that is not compatible with anything else.

Are the switches good?

ummmm not really, it uses a dome over slider design, but its very stiff with a faint click at the bottom as the rubber dome activates. It uses fujitsu peerless switches. It has some of the worst key stabilization I've ever seen in a keyboard board. If you don't press the enter key directly in the middle, it binds and won't go down. It feels like no other keyboard I've used before. And according to the manufacture sticker, it is from the early 90s, plus it uses a Ps/2 cable, so I'm not thinking protocol is an issue.

EDIT: Also, I tried plugging it in again and found that the lock lights do light up for a second, so maybe it is a protocol issue.

EDIT EDIT: I did some research, this keyboard was designed to be a direct replacement for a Model M, so protocol is most likely not an issue.
