never messed with a unichip so can't say first hand, but a search here for topic titles that contain the word unichip turned up a number of threads, and one common theme among them was people emailing unichip to get the info they needed. The other thing I noticed in those threads was that I don't think I've seen any of those unichippers around here for some time, so I don't know if any will post up or respond to PMs
