The Difference Engine
The Difference Engine was created by Charles Babbage on June 14th, 1822. The Difference Engine is a machine that was powered by steam to to print out astronomical tables. -
The Analytical Engine
The Analyical Engine was created by Charles Babbage in 1837 but was then published by Augusta Ada Byron. The Analyical Engine is a machine that uses punch cards to solve out mathematical problems. -
The Turing Machine
The Turing Machine was created and first proposed by Alan Turing in 1936. The Turing Machine was a machine were it would print out symbols on paper type in a way that seemed like a person following a series of logical instrutions. -
The ABC (Atanasoff-Berry Computer)
The ABC started to develop by Professor John Vincent Atanasoff and graduate student Cliff Berry in 1937. The ABC was a electrical computer that used Vacuum tubes. The Vacuum tubes were used for digital computation including binary math and Boolean logic. But it had no CPU. -
The UNIVAC 1 (Universal Automatic Computer I)
The UNIVAC 1 was created by Konrad Zuse in 1942. The First commercial computer was consiered as the second commercial computer. -
Colossus
The Colossus was a British computer in the 19's and it was to help them brake codes from other places. -
The EDSAC (Electronic Delay Storage Automatic Calculator)
The EDSAC was created by Maurice Wilkes and his team at the University of Cambridge Mathematical Labortory in 1946. The EDSAC was considered the first stored program electronic computer and also ran the first graphical computer game, called ''Baby''. -
The ENIAC (Electronic Numerical Integrator and Calculator)
The ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylavania in 1943. That is when they started to create the ENIAC. But they finished the ENIAC in 1946.
The ENIAC was the first eletronic general purpose computer. It was also capable of being reprogammed to solve a large class of numerical probelms. -
UNIVAC (Universal Automatic Computer)
The UNIVAC was develpoed in 1951 and it can store up to 12,000 digits in random access mercury-delay lines. -
IBM Compatible
The IBM Compatible was created in 1953 and IBM also first introduced the 701.The 701 was it's first electric computer and first mass produced computer. -
The Whirlwind Machine
The Whrilwind Machine was introduced by MIT in 1955. The Whrilwind Machine was a revolutionary computer. It was the first digital computer with a magnetic core RAM and real time graphics. -
The TX-O (Transistorized Experimental computer)
The TX-O was the first transistorized computer to be shown in the Massachusetts Institute of Technology in 1956. It was also the first computer with a transistor. -
PDP-1
The PDP-1 was first released by the Digital Equipment Corporation. After the PDP-1 ,there were many more to come. The PDP-1 was also the first minicomputer. -
HP 9100A
The HP 9100A was first marketed by Hewlett Packard and also the HP 9100A was also the first mass-marketed PC and also the first desktop computer. -
Xerox Alto
The Xerox Alto was intoduced in 1974 ,even though it never sold. The Xerox Alto was the first workshop. It had a fully functional computer, display, and a mouse. This computer was revolutionary.
