BINAC - Binary Automatic Computer
The first stored program operating computer in the
Card Programmed Calculator (CPC)
The CPC was made up of three units: a 605, a 417, and a 941. The first two were modifications of the 604 calculator and the 402 accounting machine, respectively, and the 941 was a special box containing 480 digits of additional storage using the same type of electromechanical storage used in the 417. Programs were punched into IBM cards, fed through the reader unit of the 417, with the mathematics performed by the 605, the intermediate results stored in the 605 or 941, and final results punched into cards in the 605's punch unit, or printed by the 417 print unit.
EDVAC - Electronic Discrete Variable Computer
ENIAC - Electronic Numerical Integrator and
The first electronic digital computer in the
IBM 650 - Magnetic Drum Calculator
The IBM Magnetic Drum Calculator was a numeric decimal machine.
IBM 701 - Defense Calculator
The IBM 701 was a stored program computer with a large capacity high speed electrostatic storage, intermediate magnetic drum storage, magnetic tape units and fast computing speed.
The IBM 704 was the first large scale commercially available stored program computer to employ fully automatic floating point arithmetic commands and index registers.
In 1950 Rand needed to increase its computing power significantly over what it obtained from IBM Card Programmed Calculators. After surveying commercial and university projects,
JOSS - JOHNNIAC Open Shop System
MADDIDA - Magnetic Digital Differential
Developed by Northrop Aircraft, MADDIDA was the first electronic digital differential analyzer.
SAGE - Semi-Automatic Ground Environment
The SAGE system was the first large operating program to be developed.
SWAC - National Bureau of Standards Western
SWAC was a parallel computer using Williams tube memory.
UNIVAC - Universal Automatic Computer
