If your board has brown alps I'd be surprised as brown alps are uber rare... and very heavy too.Show Image(http://i.imgur.com/ol6SdxD.jpg)
I stumbled across this board the other day and, at first, thought I might get lucky with some Hirose switches and another MX Lock since some of the older Xerox boards had them. After a little more research, I stumbled upon Deskthority thread (http://deskthority.net/photos-f62/xerox-star-low-profile-keyboard-t7869.html#p159645) that had a board that looked more like the one I'm grabbing.

Anyone have experience with these older Xerox boards? While a surprise is nice, sometimes it's also nice to have an idea before it arrives.
