Removes the false 'linear PSU with transformer, bridge and series-pass regulators' - IBM calls it a transistor switching regulator - and with it the invented rail table, the invented 9-11 kV anode figure and the unsourced '13 bipolar gate arrays' PALM board; replaces them with IBM's five rails (+5/-5/+8.5/+12/-12), the loaded and unloaded tolerance table, the protection trip points, the 5-second restart rule, the +6 V meter-reference ch...) | ||||
