So, I just did a little end-of-semester dumpster diving at my uni, and while i didn't exactly strike gold, i found an interesting little sphinx! I haven't been able to find a whole lot of info about it, but it seems to be the keyboard of one of those industrial "luggable" computers. (and please excuse the poor photography--i'm not exactly a shutterbug)

So, at first glance, it looks like an Americanized version of an ISO layout--note the blank key by the left shift. The layout looks kinda similar to some of the compact cherry layouts i've seen pictures of around here, but more on that later.

The back has some rubber feet and a lone "made in taiwan" sticker--no trace of a birth certificate, sadly.

This is the only real clue i have to the parentage of this board--Prism seems to be a manufacturer of luggable PCs.
But, remember how I mentioned it looked kinda like a cherry layout? I pulled a couple keycaps, and found this--

Which looks an awful lot like the pictures of ALPS switches. The keys also look a lot like ALPS keys, and they require a fair bit of effort to pull--i can pull Model M keys with my fingers if i'm careful, but for these, i need some serious leverage.

Unfortunately, it doesn't work--plugging it in makes my computer not boot, and hotswapping it with another PS/2 keyboard just acts like nothing's plugged in. I imagine there's a loose connection in there somewhere, but there are some screws covered by the label on the front, and it has resisted all my attempts at removal. So it appears this won't be seeing any actual usage.

However, one last twist remains--everything i've read indicates black alps are tactile, but nonclicky, but these keys have a distinct high pitched click to them (as well as a ring when they topout), which leads me to believe the switches are knockoffs. I made a ripster-esque recording (Typing a sentence, followed by home row, followed by 5 regular taps, 5 long taps and 5 light taps)
