Z1 computer
-The Z1 was a super calculator created by Konrad Zuse.
Konrad Zuse worked for the Henschel Aircraft Company in Berlin during the beginning of World War II. Being a construction engineer he needed a way to make his work easier and more reliable so he decided to make an automatic computer. To make an automatic calculator Zuse realized he needed three main components: a memory, control, and a calculator. In 1936, now 26 years old, Zuse had made the Z1, the first of three binary computers. -
Abc computer
The Atanasoff-Berry Computer also known as the Abc computer, was the first electronic computer. Created by John Atanasoff and Clifford Berry at Iowa State University in the year of 1938. The prototype took a year to make and won the team $850 dollars so that they could make the final model. Two years later they finished product weighed around 700 pounds and it could take one operation every 15 seconds. (Today the average computer can take 150 billion operations every 15 seconds).During the war t -
Harvard Mark I Computer
Harvard Mark I Computer was created by Howard Aiken and Grace Hopper in 1944, was not operational until 1959,. It was 55 feet long and 8 feet high, and weighed over 5 tons. It was used by the USA Navy for calculations concerning ballistics and gunnery. Made from almost 760,000 separate pieces including over 500 miles of wire and, and 1,400 rotary dial switches. (It required 3-5 seconds for a multiplication operation). -
UNIVAC (Universal Automatic Computer)
The UNIVAC was created by Dr. Presper Eckert and Dr. John Mauchly. Dr. Eckert and Dr. Mauchly were hired by the United States Census Bureau to keep up with the baby boom. Since the Census Bureau was only gave them $400,000 dollars, Eckert and Mauchly paid $600,000 to finish the job, but both of them were pushed to the edge of bankruptcy. The two young scientist were helped by Remington Rand Inc. in 1950. Remington Rand was the first American manufacturers of a commercial computer. -
ENIAC I
The ENIAC I (Electrical Numerical Integrator and Calculator) was created in 1946 by John Presper and John Mauchly. Sponsored by the US military, they were able to create a computer that was able to calculate artillery-firing tables to help with accuracy when shooting a certain target. John Mauchly had previously invented a lot of calculating machines and started making the plans for the ENIAC I in 1942 based on the Abc computer. -
The "Floppy" Disk
Alan Shugart was the head of the team that made the Floppydisk. The floppy disk was a flexible plastic disk coated with magnetic iron usually about oxide 8-inches wide, and could hold up to 100 KBs of data. It was a one of the most advanced way to transport data from computer to computer. It was created in 1971. -
IBM 5100
After two years of making it the 5100 was released in 1975 by IBM. It was IBM’s first portable computer and was sold for $10,000. Most of the 5100 were bought by school and small businesses. The computer itself had, tape storage, 16KB of RAM, and a built-in 5-inch screen. -
Apple I, II
Apple I and II were both made by Steve Wozniak and Steve Jobs. Apple I had a keyboard, and 8k of RAM and, a video interface. Two hundred computer were built and sold for about 10 months in the year of 1976, each computer cost about $670. The Apple II computer marked the start of the Apple company. Each computer was sold for about $1298 since it had a 6502 processor, color graphics and eventually a a floppy disk drive. -
The IBM PC - Home Computer
In 1980, in Boca Raton, Florida, twelve engineers, led by William C. Lowe and Bill gates assembled with IBM representatives for the first time to create a new personal computer (PC). Since their IBM 5100, IBM was trying to put out a more successful PC. The IBM PC ran on a 4.77 MHz Intel 8088 microprocessor; it had 16 kilobytes of memory, one or two 160k floppy disk drives, and a color monitor. The IBM PC was worth about $1,565 (equivalent to $4,000 today). -
Microsoft Windows
Microsoft was going to put Bill Gate’s new product on the shelf, but he and Rowland Hanson had not settled on a name. Bill Gate’s wanted to call it Interface Manager while Rowland Hanson wanted Windows. Microsoft Windows version 1.0 was full of bugs, crudely made, and slow. Apple wanted to put up a lawsuit against Bill Gates because Microsoft Windows violated the copyrights and patents of the company. Finally they were able to agree and sign a contract. -
The Apple Lisa
The Apple Lisa was created by Steve Jobs, the co-founder of Apple. The Lisa (Local Integrated Software Architecture). The cost of the development of the Lisa cost the company $150 million, but only 10 were ever sold for half price at $9,995 (the original price $19,000). The Lisa I had included windows, multiple tasking, a drop-down menu bar, the ability to copy and paste, folders, icons, and a mouse. The Lisa was put on the market in 1983. Two years the Lisa II was created. -
texting
Neil Papworth sent the first message from his phone to his friends computer on December 5, 1992, saying, “Merry Christmas”. Over the years phones were made so that texting was made easier, and cheaper. Companies made better phone plans, and the way that people communicated advanced dramatically. -
