I has a Keytronic controller in it, instead of the original IBM one. I wouldn't want it.
Sorry for the questions but: Does this make it worse that it has a keytronics controller? Will it change it in anyway?
Keytronic make foam and foil and rubber dome keyboards. There is no guarantee that this controller will work at all. If it does work, I would expect the matrix to be different and all the keys to be out of place. If you buy this, I would expect to have to do some work modding it to actually work again. You would need:
a genuine IBM controller or a teensy (I'd go teensy since half the work is done for you)
Then on top of that if you don't like the screw mod that was done, you will have to spend a lot of time bolt modding it
and on top of that, the keycaps on it aren't even that rare or expensive. So even ignoring all the above it's overpriced.
