Visit to the 1101 Computer
Taylor, Norman H.
A one day visit to ERA's 1101 System is discussed. The system seems to be very reliable and is in use 90-95% of the time scheduled. Marginal Checking is used with filament voltage as the method of voltage variation. This results in a high tube replacement rate. The Magnetic Drum Storage is of particular interest as its performance seems to be highly satisfactory.
