Transistorisierter Tisch-Analogrechner RAT 700 — Beschreibung und Bedienungsanleitung
Operator manual for the Telefunken RAT 700 transistorized desktop analog computer (Tisch-Analogrechner), covering mechanical construction, modes of operation, technical specifications, and operating procedures. The RAT 700 is a fully transistorized (solid-state) desktop analog computer configurable from a basic setup (10 amplifiers, 20 potentiometers) to a full configuration (19 amplifiers plus multipliers and comparators), featuring chopper-stabilized computing amplifiers with drift below 20 µV at 40°C and less than 0.1% error up to 100 Hz. The manual also addresses coefficient potentiometers, parabola multipliers, free diodes, function generators, Schmitt triggers, repetitive computation, maintenance procedures, and fault finding.
