The Commodore 64 is an 8-bit home computer released by Commodore International in August, 1982, at a price of $595 (US) with 64K of RAM and a 1Mhz processor. The C-64 is the all-time best selling single personal computer.
The Johnniac was an early computer manufactured in the early 1950's by the Rand Corporation in California. It was one of several computers inspired by the IAS computer designed by noted mathematician John von Neumann (after whom it was named) at Princeton's Institute for Advanced Study. It was removed from service in February 1966.
In 1956, the first IBM 305 RAMAC was shipped. The RAMAC was the first commercial computer that used a moving-head hard disk drive for storage rather than magnetic tape. More than 1000 systems were built before production ceased in 1961. Weighing more than a ton, it had a storage capacity of 5 megabytes.

The SAGE system was developed by MIT in the late '50s with Air Force sponsorship to counter the threat of a manned bomber attack by the Soviets. It became operational by 1963 and remained in service until 1983. The project required over 800 programmers and the technical resources of some of America's largest corporations. With 60,000 vacuum tubes and weighing in at 250 tons, the SAGE system was the largest, heaviest and most expensive computer system ever built.
An Enigma machine is any of a number of advanced electro-mechanical rotor machines used for the encryption and decryption of secret messages. Several types of the Enigma machine were developed before and during World War 2. The most complex Enigma type was used by the German Navy. The machine has become well-known because Allied codebreakers were able to decrypt a huge number of messages which had been enciphered using the Enigma. The information gathered from this source was a substantial aid to the Allied war effort.
