"Charles Babbage (1791-1871), computer pioneer, designed the first automatic computing engines. He invented computers but failed to build them. The first complete Babbage Engine was completed in London in 2002, 153 years after it was designed. Difference Engine No. 2, built faithfully to the original drawings, consists of 8,000 parts, weighs five tons, and measures 11 feet long."
Video is a little shaky because I'm holding my little camera with one hand, over my head, and zoomed in.

CDC 7600 at Lawrence Livermore National Laboratory, c. 1971
CDC 7600 (serial number 1), Control Data Corporation, 1971
Memory: 512K (60-bit) Core
Speed: 36 MFLOPS
Cost: $5,000,000
“The CDC7600 was the follow on to the 6600, designed by Seymour Cray. About five times faster than the CDC 6600, scientific and government institutions primarily used both machines to execute large mathematical programs written in FORTRAN. Scientists at Lawrence Livermore National Laboratory used this machine to design nuclear weapons and, like most CDC customers, wrote much of their own software. A very large machine, the 7600 had over 120 miles of hand-wired interconnections. It was Freon cooled.”

In 1953, Shell Labs in Amsterdam was the first site in the Netherlands to use an electronic computer in a production environment. The computer was a Ferranti Mark I*, designed at Manchester University (with help from the legendary Alan Turing) and built by British company Ferranti. The Amsterdam model was called MIRACLE, for "Mokums (Amsterdam's) Industrial Research Automatic Calculator for Laboratory and Engineering", but some people nicknamed it "May It Replace All Chaotic Laboratory Experiments". My mother was one of its programmers and kept a photo album.
This was a monitor of the computer, that could only show binary digits; no characters.

The Rand Corporation, Johnniac, c. 1954
Memory: 4K (40-bit) Core
Speed: 40,000 Add/s
Cost: $470,000
“The Johnniac was one of seventeen custom-built machines inspired by John von Neumann’s design at the Institute of Advanced Study. This design specified a binary, bit-parallel computer optimized for scientific calculation. These first generation computers played a crucial role in convincing IBM and other major manufacturers to move beyond punched card technology and embrace the electronic stored program computer as a commercially viable product. Apart from the original IAS machine, the Johnniac is probably the only one of these machines to have survived.”

WISC, University of Wisconsin, c. 1955
Memory: 1K (50-bit) Drum
Speed: 100,000 Add/s
Cost: $50,000 (est.)
“The WISC (Wisconsin Integrally Synchronized Computer), designed by Gene Amdahl while completing his Ph.D. in theoretical physics, was built at the University of Wisconsin between 1950 and 1955. It was used to train electrical engineering students in the then-new field of computing. The machine’s memory was rotating magnetic drum, the rotation time of which determined the overall speed of the system. It could perform four arithmetic operations at once, a unique feature for the time. After graduation, Amdahl joined IBM and played a key role in the architectural design of several important systems including the groundbreaking System/360.”

Table of Logarithms by Charles Babbage, 1827
Babbage’s logarithms tables, first published in 1827, had a reputation for exceptional reliability. Babbage did not compute the tables from scratch but used reputable tables by Francois Callet as the starting point. Nine separate stages of painstaking checking were used to verify correctness. The results were stereotyped and the volume remained in print for over a century. This volume was published in 1912.
The Babbage Engine
"Charles Babbage (1791-1871), computer pioneer, designed the first automatic computing engines. He invented computers but failed to build them. The first complete Babbage Engine was completed in London in 2002, 153 years after it was designed. Difference Engine No. 2, built faithfully to the original drawings, consists of 8,000 parts, weighs five tons, and measures 11 feet long."

I was in The Teacher Building in Glasgow today for an event on Federated Identity Management. In the basement, just outside the toilets, were these three display cases. Some of the items on display bring back memories. Some from my own experience, others from tales of the Olden Days.
The Millionaire Calculator is a mechanical calculator from 1899 that was built in Switzerland.
A little known fact is that mechanical calculators date all the way back to the 1600s. In fact, the first (mechanical) computer was conceived and designed by Charles Babbage in 1822. (Although, a functional computer was not built until over a century later).
