Some pictures of old computers…..really we changed a lot

A computer generation...

1. AVIDAC, Argonne's first digital computer, began operation in January 1953. It was built by the Physics Division for $250,000. Pictured is pioneer Argonne computer scientist Jean F. Hall.


2.A press conference for what is considered the first computer, the Electronic Numerical Integrator and Calculator (ENIAC), was held at the University of Pennsylvania on February 1, 1946. The machine (shown here with a technician) took up an entire room, weighed 30 tons and used more than 18,000 vacuum tubes to perform functions such as counting to 5,000 in one second. ENIAC, costing $450,000, was designed by the U.S. Army during World War II to make artillery calculations. The development of ENIAC paved the way for modern computer technology–but even today’s average calculator possesses more computing power than ENIAC did.



3. The first ever computer in Latvia was developed and made at the start-up Institute of Electronics and Computer Science in early sixties. No computers were made industrially in USSR at that time. Therefore successful completion of that project certainly represented a significant achievement. Built on a lot of vacuum tubes, the computer actually worked well and was used for supporting research activities for several years till the time when it became possible to replace it by a more powerful industrially made computer.


4.The CSIRAC was Australia's first computer.

The name stands for CSIR originally stood for "Council for Scientific and Industrial Research". This name was in effect from 1926 to 1949.


5. A man and woman working at a Ferranti Pegasus computer. This computer was a classic 1950s/1960s mainframe installation, taking up the majority of space in a room.


6. The computer history at NTNU is much older than the computer departments. The very first computer at NTNU was called DIANA, or DIfferential ANAlysator. This was an analog electronic computer built by Jens Glad Balchen and the Division of Cybernetics in the years between 1952 and 1955.


7.Amdahl Corporation, Sunnyvale, CA. A computer manufacturer founded in 1970 by Dr. Gene Amdahl, chief architect of the IBM System/360. In 1975, Amdahl installed its first IBM-compatible mainframe, the 470/V6. In 1979, Amdahl left the company he founded to form Trilogy, which tried without success to make the world's largest chip based on wafer scale integration.


8. First ever apple computer running windows. This is anApple II with a monochrome screen and PC emulator hardware installed. The board was called the 88 Card, "the only fully functional 8088 processor for the Apple II personcal computer


9.First hard disk The rotating drum technology allowed ERA to deliver the world's first production stored-program computer* (ATLAS - ERA 1101) to a customer site in October 1950. The engineers making the installation delivery to the National Security Agency predecessor were Frank Mullaney and Jack Hill. As shown in the photo below, these drum products came in various sizes. They were first used in several classified processors, then in the early 1100 computer series and the UNIVAC SS-80 and SS-90 computers. Dr. Cohen and Sid Rubens are credited with patenting the rotating magnetic drum.

The drum development engineers and management shown in this early 50's photo, left to right are:

William Keye, Arnold Hendrickson, Robert Perking, Frank Mullaney, Dr. Arnold Cohen, and John 'Jack' Hill.


And this is how it installed to the computers
