I don't think that Kevin missed this himself, but for those out there that plan to replace their power supplies, remember to check out those voltages carefully when you install. Both of the 3B1 power supplies I bought recently were badly out of trim (How about +4.3V & +10.5V). Prior postings cover the voltage & pinout assignments, email to me if you want a copy. ___ Steven C.
