Hubby did actually do that...Except at the time we thot they were all the same 2595...Thot it was a little weird that they have diff color under keys and diff logos, etc, but this was literally 2 days before our wedding and we were sleep deprived and in a massive rush to try to get stuff done......It wasn't until tonight (I just got back from Ft Knox where hubs is stationed 2 days ago) that i was finally able to grab a board and start scrubbing off the grime..Which is when I noticed the "aftermarket" stickers, got curious, and uncovered the 6 different model numbers...They range in age from 1987-1997. I don't have the first clue which special keys go with which boards and it honestly makes my brain hurt just contemplating sorting thru about 1400 keys (yes...hubs popped quite a few of the base keys also cuz the boards were *that* crusty. This whole thing has been a massive headache and I'd like to throat punch the jerk on eBay. It's one thing for me to unknowingly buy a bunch of terminal keyboards..OK, my bad..But be a complete D to me about it *and* stick fake labels on most of them? grrrrrrrrrrrrr!!!!!!!!!))
