A repair for a friend recently, needed a 64mb Dimm testing but it was an old 5 Volt Dimm. Most modern machines would not support this old standard, but one of my old Pc's did so the Dimm was tested and the problem resolved. ( just for the record that Dimm was for a MAC 5500/225 PPC) There are so many resources on the net for PC products and drivers. I you want to repair an old PC's then. Start Here at :-"Hand me down PC Page" It is an online book, of about 10 years ago, and a good place to start for information on elderly PC's.
