The Complex Number Calculator (CNC)
In 1939, Bell Telephone Laboratories completes this calculator, designed by scientist George Stibitz . Stibitz stunned the group by performing calculations remotely on the CNC (located in New York City) using a Teletype terminal connected via to New York over special telephone lines. This is the first example of remote access computing. (computer history.org) -
ENIAC
the ENIAC computing system was built by John Mauchly and J. Presper Eckert at the Moore School of Electrical Engineering of the University of Pennsylvania. it is over 1,000 times faster than any previous computer. It used about 18,000 vacuum tubes and weighed 30 tons. [computerhistory.org] http://www.computerhistory.org/timeline/computers/ -
transistor
Easily the most important components in computers, transistors can switch tiny electric currents on and off or amplify them .Transistors that work as switches act as the memories in computers, while transistors working as amplifiers boost the volume of sounds in hearing aids (timetoast.com) -
Ferranti Mark I Sold
The title of “first commercially available general-purpose computer” probably goes to Britain’s Ferranti Mark I for its sale of its first Mark I computer to Manchester University. A British government contract spurred its initial development but a change in government led to loss of funding and the second and only other Mark I was sold at a major loss to the University of Toronto, where it was re-christened FERUT.

Leo-I (Lyons Electronic Office I)
Modeled after the Cambridge University EDSAC computer, the president of Lyons Tea Co. has the LEO built to solve the problem of production scheduling and delivery. Lyons went into business manufacturing computers to meet the growing need for data processing systems in business. The LEO was England’s first commercial computer and was performing useful work before any other commercial computer system in the world. (Computer history.org) -
Operating System
IBM rolls out the OS/360, the first mass-produced computer operating system. Using the OS/360, all computers in the IBM 360 family could run any software program. Already IBM is a giant in the computer industry, controlling 70% of the market worldwide. ( PBS.ORG) -
Minicomputer
Digital Equipment introduces the PDP-8, the world's first computer to use integrated circuit technology. Because of its relatively small size and its low $18,000 price tag, Digital sells several hundred units. (pbs.org) -
ARPANET invented
ARPANET stands for advanced Research projects Agency network and was the first computer network. it was created for military purposes by the DOD and used the TCP/IP protocol. [wikipedia] https://en.wikipedia.org/wiki/ARPANET -
BARCODE
The first shipments of bar-coded products arrive in American stores. Scanners at checkout stations read the codes using laser technology. The hand-punched keyboard cash register takes one step closer to obsolescence. (PBS.ORG) -
Super Computer
Cray Research, Inc. introduces its first supercomputer, the Cray-1, which can perform operations at a rate of 240,000,000 calculations per second. Supercomputers designed by Seymour Cray will continue to dominate the market; the Cray 2, marketed in 1985, will be capable of 1,200,000,000 calculations per second. (pbs.org) -
Apple I
Apple I was released by Apple Computers. it was the first computer with a single- circuit board. it could hold 4 KB standard
expandable to 8 KB or 48 KB using expansion cards. Steve jobs came up with the idea to sell it. The Apple I went on sale in July 1976 at a price of US$666.66 [Wikipedia] https://en.wikipedia.org/wiki/Apple_I -
PC
In January "Time" names its 1982 "man" of the year -- the personal computer. PC's have taken the world by storm, dramatically changing the way people communicate. IBM dominates the personal computer market, benefiting both from the production of its own machines as well as "clones" produced by other companies (pbs.org) -
Graphic User Interface
Apple files a suit charging that Microsoft has pirated Apple's user-friendly graphical interface. The suit will fail, and Microsoft's star will continue to rise. By the mid 1990's, Apple will be experiencing a painful and public financial shakeout. ( pbs.org) -
