OK, so you guys were right, these keycaps are a pain in the ass to get off. I was actually mistaken earlier since I only got a quick glance --- this is one of the models with the Windows keys. I pried off one of the caps and it doesn't say Alps on it like I think I've seen in some pictures; they're black/white with "2F71" lettering on them. I guess this makes them complicated Alps?
The board itself seems like it's in more or less OK condition. There's some really bad yellowing, a missing leg, no cover, and the backspace sometimes sticks, but beyond that it's OK. Always fun to try out a new type of switch (for free, anyway). Now I just need to get used to this god-forsaken two-row enter and moved backspace. Thanks for the help earlier in the thread!
