Donner Model 3000 Analog Computer Operating Handbook
Operating handbook for the Donner Model 3000 analog computer, a DC electronic differential analyzer with ten operational amplifiers (pentode-input, cathode-follower output) capable of solving differential equations. Covers specifications (open-loop gain >10,000, bandwidth to ~10,000 cps, output ±100V at 5mA), theory of operation including summing, integration, sign changing and scaling, operating instructions, and servicing. Includes schematic drawings for the power supply and amplifier/switching circuits, plus problem board layout.
