The ERA 1101/UNIVAC 1011
In 1950, the Engineering Research Associates invented the ERA 1101, in St. Paul, Minnesota. It was the first stored-program computer to be successfully rehomed. Its mass was that of 7.6 tons. -
The SEAC (Standards Eastern Automatic Computer)
The SEAC was one of the very first stored program computers in the United States. It used an all-diode logic system, which was much more reliable and advanced than the common vacuum tubes used in computers during this era. In 1957, the first image ever scanned into a computer was done by Russell Kirsch, who used the SEAC to accomplish this task. -
SWAC (Standards Western Automatic Computer)
The SWAC, invented by the NBS (National Bureau of Standards), discovered five new prime numbers by way of numerical analysis. It used pre-existing technology that had been fine-tuned to make this a rather stunning machine. -
LEO-1 by J. Lyons and Co.
Lyons Tea Co. introduced the LEO-1 to handle the scheduling and delivery of the cakes from their bakery. It specialized in processing and helped effectively plan out routines for the company. The data processing units designed for business became a necessity in an ever growing computer run world. Today, we take this kind of scheduling for granted as many aspects of life involve scheduling. -
IBM 650
The IBM 650 was a magnetic drum calculating machine that became the first ever mass-produced computer. The large volume of storage that it could hold combined with the speed it used to retrieve said data made it extremely popular in universities where many young students first learned to program.
