EAI 180 Computer Operator's Reference and Maintenance Manual
The Operator's Reference and Maintenance Manual for the EAI 180 Analog-Hybrid Computer covers initial set-up, operating procedures (readout and meter control, display and mode control, digital control), and detailed descriptions of all computing components including linear (summers, integrators), non-linear (function generators, comparators, multipliers), and digital logic elements. The manual also includes maintenance procedures for the main frame and each panel type, three appendices on unit scaling, transfer-function simulation, and representation of constraints and nonlinearities, plus a full set of circuit diagrams for all major sub-assemblies. The EAI 180 is a compact, solid-state general-purpose analog-hybrid computer designed for office or classroom use, rated for 240V/50Hz or 110V/60Hz operation.
