I've been using the same IBM Model M keyboard for about 6 years now. I never thought I would see the day when it would quit working. I love this keyboard -- the buckling springs deliberately and assuredly clicking and clacking beneath my fingers blow the pants off any cheap-ass keyboard you get for "free" with your factory Dell PC. It's amazing that the best keyboard ever made was actually one of the very first. Created in 1985, the Model M set the standard to beat, but the quality of PC keyboards over the years has only gone downhill. Thank goodness Unicomp still makes these things. Otherwise, I'm not sure what I would ever replace this keyboard with... maybe a Das or a Deck.
Luckily, I don't have to replace it. It hasn't died yet, and probably never will.
Chris McDonough recently wrote an excellent article on the 25 years of the Model M. Since reading it, I've been thinking quite a bit about my trusty Model M and I decided to give it an early 25th birthday present: some new colors!
I followed a guide from Overclock.net describing the process of applying rit dye to the keys. I've used other keyboards that had paint jobs on them before, but the rit dye process is soo much nicer. With paint, you always get a sticky paint feel on the keys and of course it also covers up the letters on the keys permanently. The rit dye, on the other hand, permeates the plastic and leaves no residue on the surface at all. In fact, you can still see the letters quite well.
I liked the red and brown combination used in the Overclock.net guide, although I left the original color differentiation of the model M intact: letters and numbers red, and the meta keys and some of the F keys brown. The red keys turned out fantastic, the letters on them are very distinctive. However, the brown turned out a bit differently; being much darker, almost black, it all but obscures the markings on the keys. No big deal though, I guess my new Model M is half-way to a Das Ultimate after all. :)
