So I'm in the process of retrofitting this Dell AT101W:

I've opened up one of the ALPS switches, and removed the "tactile leaf". But I can't yet decide if this is what I want.... This is an old board, and leaving it in there makes key downstrokes sound very "sandy", almost like it's rubbing against sand paper. Removing the tactile leaf and it's a very smooth linear downstroke that feels "clean", almost reminds of my cherry brown.
Another interesting thing, on a whim, I bought this $5 rubber-dome PC Concepts board.

Once taken apart, its keys sits nicely on these "trays". The keys push down on the rubber dome via a white "stem" (the little white pieces on the floor in picture above). This stem is very similar to the plunger on the ALPS, so much so that the keys are identical!!
Here's a comparison. Top is a shift key from the PC Concepts rubber-dome, bottom is from the DELLA AT101W.


Not only do the these keys fit right on the Dell ALPS, even the metal stablizers are the same. So now I can replace the Dell's old keys with these relatively newer keys.
