The Complex Number Calculator (CNC) is completed.
In 1939, Bell Telephone Laboratories completed this calculator, designed by researcher George Stibitz. In 1940, Stibitz demonstrated the CNC at an American Mathematical Society conference held at Dartmouth College. I chose this becasue it was a big accomplishment, that help further our field in computers and calculators. -
"First Draft of a Report on the EDVAC"
John von Neumann wrote "First Draft of a Report on the EDVAC" in which he outlined the architecture of a stored-program computer. Electronic storage of programming information and data eliminated the need for the more clumsy methods of programming, such as punched paper tape — a concept that has characterized mainstream computer development since 1945. I chose this becasue we were able to talk about the advancements being made and the people involved in it. -
the Lyons Electronic Office
England´s first commercial computer, the Lyons Electronic Office, solved clerical problems. The president of Lyons Tea Co. had the computer, modeled after the EDSAC, built to solve the problem of daily scheduling production and delivery of cakes to the Lyons tea shops. After the success of the first LEO, Lyons went into business manufacturing computers to meet the growing need for data processing systems. I chose this because advances were not only being made in the US, but in th UK as well. -
IBM shipped its first electronic computer
During three years of production, IBM sold 19 machines to research laboratories, aircraft companies, and the federal government. I chose this because it effected not only people at home, but people at aircarriers and other larger companies. -
CDC´s 6600 supercomputer
designed by Seymour Cray, performed up to 3 million instructions per second — a processing speed three times faster than that of its closest competitor, the IBM Stretch. I chose this because it was a big improvement on computers and especially supercomputers. It allowed us to work faster and quicker. -
HP-2115 for computation
offering a computational power formerly found only in much larger computers. It supported a wide variety of languages, among them BASIC, ALGOL, and FORTRAN. I chose this becasue it was a improvement on regualr computers and how we can use them in our own homes today. -
Apple I
Steve Wozniak designed the Apple I, a single-board computer. With specifications in hand and an order for 100 machines at $500 each from the Byte Shop, he and Steve Jobs got their start in business. In this photograph of the Apple I board, the upper two rows are a video terminal and the lower two rows are the computer. I chose this becasue Apple issuch a huge company and this is who began the whole thing. -
Atari 400 and 800 Computer.
Atari designed two microcomputers with game capabilities: the Model 400 and Model 800. The two machines were built with the idea that the 400 would serve primarily as a game console while the 800 would be more of a home computer. I chose this because it was a huge improvement on gaming consoles and how we use our smaler technology today. -
Macintosh
Apple Computer launched the Macintosh, the first successful mouse-driven computer with a graphic user interface, with a single $1.5 million commercial during the 1984 Super Bowl. Based on the Motorola 68000 microprocessor, the Macintosh included many of the Lisa´s features at a much more affordable price: $2,500. Apple is such a big company that this was a very big deal. -
The 68030 microprocessor.
Motorola unveiled the 68030 microprocessor. A step up from the 68020, it built on a 32-bit enhanced microprocessor with a central processing unit core, a data cache, an instruction cache, an enhanced bus controller, and a memory management unit in a single VLSI device — all operating at speeds of at least 20 MHz. I chose this because it was performing at speeds of at least 20 MHz. Which is a very big accomplishment!
