EAI 680 Maintenance Pocket Guide

Read the PDF (27 pp) ↗

A compact pocket guide prepared by the EAI Technical Training Department to assist technicians maintaining the EAI 680 analog/hybrid computer, published October 1969. The guide covers operating equipment (patch cords, pins, connectors), a full inventory of major computing trays (analog, control, and logic types with old- and new-series part numbers), patch panel overlays, special tools and accessories, expendable supplies for peripheral units (8850 plotter, 8875 recorder, 8880 display, 8881 monitor oscilloscope), connector repair kits, fuses, lamps, and a semiconductor replacement guide listing direct replacements, substitutes, and special-category diodes and transistors. Console adjustment diagrams, bus layouts, plug-in component and integrated-circuit pin layouts, and chassis connector layouts are included as fold-out illustrations.

These trays are identical with their equivalents in the Old Series column except that 6.0831 or 6.0842 Amplifier Cardsare suy plied (the 6.0842 Ampffier Card has the over-voltagelimiter built on the ftwin circuit board; the 6.0831 is electrically identical, but the over-voltagelimiter is on a small outboard circait card)- The 70.00251 and 77.0023 trays have no OId Seriesequivalents. 3.
