Jim most of my 'interesting' machines - both S/3s, S/38, 1800, big disk drives - do need three phase 60Hz. The 2741s, 3741, 5496, S/32, S/34, & S/36 are single phase but almost certainly need 60Hz for power supplies and/or disk drives On the plus side all of the stuff I brought over from the UK will work fine - includes pdp-15s, pdp-12s, KL & KS 10, and a bunch of RK05s with 50Hz pulleys! They all take 240V 50Hz. Mike
