680 Scientific Computing System Reference Handbook
This reference handbook covers the EAI 680 Scientific Computing System, a large-scale analog/hybrid computer. It describes all computing components in textbook format, including combination amplifiers, summers, servo-set potentiometers, multipliers, fixed and variable diode function generators, comparators, logic trays, and the patch panel layout. A fully expanded 680 features 156 amplifiers, 120 servo-set pots, 24 multipliers, 18 variable DFGs, and 24 comparators; the handbook guides programmers from machine organization and the signal selector system through mode control, time scale selection, and appendices on specific applications and scaling techniques.
