The Analog Computer Museum's Collection

The following list contains all of the machines in the analog computer museum. Unfortunately not all machines are described in detail currently due to my lack of time, but this will change in the near future. Some machines are mentioned even without a photo which is due to the fact that the museum is being expanded and some machines are stored in warehouses and are not directly accessible.

Aritma AT (Prague)
	ADT 3000.
	The MEDA 43 analog/hybrid computer. This machine was designed and built in the former czechoslovakia and found widespread use in the countries behind the iron curtain.
BBC
	Table top analog computer made by BBC.
Donner
	Donner 3000 analog computer from 1958.
Dornier
	The Dornier DO-80 analog computer. The smallest system built by the German manufacturer Dornier.
	DO 910 hybrid computer.
	The Dornier DO-960 analog computer. This system is one of the most sophisticated analog computers ever built.
ELA
	ELANAG.
Electronic Associates Inc. (EAI)
	EAI 180.
	EAI 185.
	EAI 380.
	EAI 580.
	EAI 680.
	EAI 1000.
	The EAI-2000 analog computer. This is one of the last analog computers built by this famous company. It is a rather small hybrid computer system featuring a built in digital prozessor with a control terminal which allows complete control of the digital part as well as the analog part of the machine.
	EAI function generator.
	EAI MiniAC.
	EAI Pacer-700.
	The EAI Slow Scan Oscilloscope.
	The EAI TR-10 analog computer. This is the first transistorized table top analog computer built by EAI (1961).
	EAI TR-48.
General Dynamics
	Some General Dynamics analog computer modules which have been used in the control of a nuclear power plant.
George A. Philbrick Researches (GAP/R)
	George A. Philbrick Researches Adder.
	Various amplifiers made by George A. Philbrick Researches.
GTE
	GTE EA-22 table top analog computer.
Heathkit
	Heathkit EC-1 analog computer.
Hitachi
	The Hitachi-240 analog computer. This system has 40 chopper stabilized operational amplifiers and a lot of special functions, but is quite a challenge to repair and maintain.
	A Hitachi 303e analog computer. This system features the rather unusual machine unit of +/-50 V.
Non commercial
	Homebrew analog computer made at the TU-Darmstadt in the 1970s.
	During the last couple of days I built the small analog computer designed by Dr. Vogel and documented my progress with quite some pictures and some remarks concerning necessary changes which were necessary since I could not get hold of some special parts.
	The museum got a wonderful donation from Rolf Englert - a special purpose analog computer which implements a pharmaco-kinetic model used in teaching pharmacology. This machine can be seen here.
Solartron
	The Solartron Analogue Tutor. A small tube based system intended primarily for educational purposes.
	Solartron Miniscpace.
Telefunken
	The TELEFUNKEN DEX102 "Digitalzusatz". This was a digital extension for the RA742 table top analog computer. Both devices together build a small hybrid computer.
	The TELEFUNKEN OMS 811 dual beam oscilliscope. This oscilloscope was especially designed to be used in conjunction with TELEFUNKEN's transistorized analog computers. It features two channels with independent x- and y-deflection as well as synchronisation mechanisms for camera control, etc. Here you can find some notes about the restoration of such an oscilloscope.
	This is another one of my personal favourites: The first analog computer ever made by TELEFUNKEN. This machine is the one and only engineering model which was created from 1955 to 1956 by TELEFUNKEN (Ulm).
	The TELEFUNKEN RA741 analog computer.
	The TELEFUNKEN RA742 analog computer - this was the last of TELEFUNKEN's very successful table top analog computers.
	This machine, the Telefunken RA 770, is, in my humble oppinion, the best and most fascinating electronic analog computer ever built by any company. With this machine a dream dating back to the days of my childhood finally came true.
	The TELEFUNKEN RAT700 analog computer - this was the first of TELEFUNKEN's very successful table top analog computers.
Vero
	Small educational analog computer made by Vero.
