Okay, great.
It's just that the keys are so unevenly yellowed, makes it look a bit strange. I personally don't really care about that (the kb I'm using now is about as yellowed as the FK), as long as the switches are in good health I'm happy.
We'll be harassing our vintage Sun hardware-provider either tomorrow or Thursday, hopefully we'll get a couple of those sweet Ultra 5's to pass along. I don't know what they weigh, but I think shipping for one of them will be somewhere between 40-80 EUR. I don't think the SparcStation 5's are worth that much (too slow, obsolete SCSI interface), but an Ultra 5 might be. Will keep you informed with what we manage to score.
I'm also really looking forward to getting the keyboard! Thanks again!
