System configuration: PDP-11/70 CPU KB11-C w/FP11-C, 0 RH70's, 1 DL11W, 1 RX211 MK11 1024KW BA11 w/1 DZ11, 1 RL11, 1 KLESI, 1 DELUA, 1 UDA50 RX02 SA72 w/4 RA72 RL02 TU81+ LA120 The entire system is fed with a single 220V 30A circuit which is split into two 110V 30A circuits through an 861-D power controller. Configuration Run current Peak Current L1 L2 L1 L2 CPU only 5.8A 5.2A 6.2A 5.7A CPU+MK11 5.8A 8.9A 6.2A 10.5A CPU+MK11+BA11 9.9A 8.9A 14.7A 10.5A Full load at idle 12.1A 14.1A 17.4A 17.5A Full load with all 12.2A 15.4A disks spun up, tape loading, CPU running EMKA diag. The total current draw would be the sum of the values from L1 and L2. These are observed values from my own system. Your system will never be exactly the same as mine. Don't under-estimate the AC circuits to the equipment. -- Doug Carman pdp11(a)bellsouth.net
