Timeline according to the textbook assigned to my class at SBCC, by Mitch Aki. 2013
These dates aren't in the textbook, I found them on wikipedia.
William Oughtred created the first slide rule in 1621. It remained in use as an essential tool through the 1960s.
Mechanical device that could be used to perform addition, subtraction, multiplication, and division.
Similar to the Pascaline.
Thomas de Colmar's Arithmometer was the first mass-produced mechanical calculator.
Babbage worked on the device for 11 years, but never created a working version of the device.
Hollerith incorporated The Tabulating Machine Company in 1896. Became IBM in 1924.
John V. Atanasoff and Clifford E. Berry, a professor and grad student respectively, from Iowa State University created the first computer to use vacuum tubes instead of mechanical switches for processing circuitry.
Officially named the IBM Automatic Sequence Controlled Calculator it was moved to Harvard where it acquired its nickname. It was also decimal-based instead of binary-based.
The world's first working programmable, fully automatic computing machine. Finished in 1941 and destroyed in 1943 by Allied bombing during WWII.
COLOSSUS successfully broke codes during WWII giving Allies an advantage.
Designed to calculate trajectory tables for the military, it wasn't finished until after the end of WWII. It was dedicated in 1946 to make atomic energy calculations and missile trajectory tables.
AT&T Bell Laboratories.
The first commercially successful digital computer. After its completion, Remington Rand, IBM's rival, bought the Eckert-Mauchly Computer Corp.
Made possible by independent research by Jack Kilby of Texas Instruments and Robert Noyce of Fairchild Semiconductor.
The first commercially successful minicomputer
Ted Hoff developed the first microprocessor, the Intel 4004.
These processors were used in Apple II and Commodore PCs.
Forerunner of today's personal computer.
Considered the first commercial microcomputer
Enhanced 8080 microprocessor introduced by Zilog
$10,000 price tag...
Cheaper than the Lisa.
Computer industry milestone...
