Totzeitglieder für den DO 80 Analogrechner — Beschaffungs- und Entwicklungsunterlagen
A compilation of internal correspondence, technical descriptions, circuit diagrams, and supplementary material relating to the development and procurement of dead-time (Totzeitglied) plug-in modules for the Dornier DO 80 analog computer, dated 1973–1975. The core preliminary description documents an 8-bit A/D and D/A converter architecture with a 100-word shift register, providing adjustable dead-time delays from 1 ms to 10 s in three ranges, selectable via a continuously variable input; the module occupies one single-width DO 80 slot. Supporting material includes Siemens and Dornier procurement letters, internal distribution memos, Helipot resistor-network and AEG-Telefunken LZG 100 delay-unit data sheets, and an English-language Monte Carlo simulation article from Electronic Design (February 1973).
