I felt like i have to restore my first vintage keyboard i own, chicony kb-5161a with blue alps switches. So i started it few days ago.
Today after cleaning and restoring every switch and solder them back. Then with pluged on keyboard and solder iron i picked up keyboard and somehow touch iron. When i looked after that at keyboard all thre lights were truned on. I touched a controler and fast diagnose. It is dead. I know what i did was dumb. But also i think is quite funny, idk how i should feel. Its quite... sad?

Anyways. Im looking for help for making it alive again. I would like to replace controler but i think it is unussual and hard to find but maybe somebody of you have one, maybe whole pcb that i can buy. Advices will also be useful.

Dang that sucks, but I guess it happens to the best of them. Good luck with getting a new controller or PCB!

F, my dude.

I know your pain, but it was with my NTC 6151N, the first Alps board I ever had, blue Alps too for that matter. Somehow, I managed to brick it when trying to figure out if I could make it NKRO with diodes.

That sucked, but bricking a 5161A PCB is a huuuge oof. It is indeed very difficult to find that model, especially with blue Alps.

I finally found a 5161A a while a back and swapped its PCB into another NTC. That felt like finally getting what I had wanted after all those years.

Best of luck in finding a solution.

Okay, so this actually happened to me with my Acer KB-101-A. My solution was to handwire it all and make it a usb compatible, programmable keyboard. I can help you go through with this if you would like. If you have diodes on it, it will be significantly easier. Seeing that it is the A model, this should definitely be doable, to simply wire up the matrix to a teensy 2.0++, and create a firmware for it.

It happened to me as well with an NTC white alps board. Switch donor is what i advice, build a custom with them.

This is too good keyboard to make it as switch donor. It don't deserve this end

I think of it as a last resort.
I would like to keep original shape of keyboard/ components and to use original cable. So for now i'm looking for pcb/ controller. If there is gonna be not response then i will contact with you :)

I agree with this, finding a replacement controller is unlikely given how old the board is. Plus, you will have NKRO :)
