I got this Unicomp 2009 Model M at a good price in the local classifieds, and I have to say it compares fairly well to my 1987 Model M.
However, after using it for a moment, I noticed that the right shift felt ... weird. Crunchy, very badly stabilized. I proceeded to pull off the keycap, and found this:
A spring where the stabilizer insert should be - and not just that. It's complete with flippers, and if I insert two 1U keys in the barrels, the right one registers as RShift, while the left one also registers a keypress, however without being bound to anything.
So, what the ... is going on? One of course immediately begins to think "Ooooh, split shift!", but it came with a normal, wide RShift, and the left key is, as mentioned, not in use. When testing with xev, it just registers as NoSymbol:
Code: Select all
