I posted this image a couple of weeks ago:
I friend of a friend pulls gold out of old computers for some extra cash. He has managed to fill multiple sheds full of old computer components.
Fortunately, keyboards don't have much gold in them, and so he let me take a bunch of them. And by a bunch, I mean a little over 60. Pictured below is most of the "keyboards of interest". I found a couple dozen more after I took the picture.
I found 17 terminal Model Ms
I also found 27 regular Model Ms. 15 of those are late-era blue labels (generally from 1995-1997). Three are grey labels. One is a silver label. The rest are Lexmark and AT&T branded. A lot of them are missing keys.
There were quite a few "keyboards of interest" with mechanical switches which I grabbed. I don't recognize most of them, but I suspect some of you will. I will be taking individual pictures once I clean them. There are a few Dell keyboards with linear switches, some HP keyboards with some sort of switch that I don't recognize. Not all of them are pictured here.
I also found four Model Fs, of various makes.
I don't recognize a lot of the keyswitches. I'm pretty sure this one is mechanical.
And of course, the super-majority of what I found were awful, mushy feeling things.
I've tested a few, and so far every single one has worked fine. It's going to take forever to clean these. All of these will go up on eBay eventually.
