EASE OF MAINTENANCE – Construction is chiefly of flat chasses mounted on racks freely accessible on both sides making parts conveniently accessible for maintenance. Extensive use of standardized plug-in components permits rapid replacement and test and repair if needed of suspected components without shutdown of machine. Various manual controls are provided for the convenience of maintenance personnel including operation for one cycle or one instruction at a time, repeat of one operation, synchronization of test oscilloscopes, etc. Tape operation is checked continually by use of an auxiliary channel using the so-called “odd” pulse check per character.
