The first laptop computer

10 Jun

Released in 1981 by the Osborne Computer Corporation, the Osborne 1 is considered to be the first true portable computer – it closes-up for protection, and has a carrying handle. It even has an optional battery pack, so it doesn’t have to plugged into the 110VAC outlet for power.

While quite revolutionary, the Osborne does have its limitations. For example, the screen is only 5″ (diagonal) in size, and can’t display more than 52 characters per line of text. To compensate, you can actually scroll the screen display back and forth with the cursor keys to show lines of text up to 128 characters wide.

The Osborne was designed with transportation in mind – it had to be rugged and able to survive being moved about. That’s one reason that the screen is so small – a larger and heavier screen would be more susceptable to damage.

The two pockets beneath the floppy drives work great for floppy disk storage, although the Osborne modem also fits perfectly in the the left pocket and plugs into the front-mounted “modem” port.

Designed as a true portable computer system – it can be considered airline carry-on luggage, and it will fit under the passenger seat of any commercial airliner.

Old Photos of the First Generation Of Computers

24 Feb

Computers, and technology in general, have come a long way in today’s world. The modern world is actually shaped and defined through the usage of computers, those neat little gadgets that do the hard work for you. Modern computers are also perfectly capable of entertaining, organizing, reminding, even surprising you. That wasn’t always the case. Here is glimpse of the history of computers and their humble beginnings. These computers may not have been as powerful as modern computers, but they’re old black and white photos are intriguing nevertheless. If for no other reason, then because those old computers were capable of filling a whole room with their robust circuitry. Enjoy these old photos of the first generation of computers.

AVIDAC, Argonne’s first digital computer, began operation in January 1953. It was built by the Physics Division for $250,000. Pictured is pioneer Argonne computer scientist Jean F. Hall.
A press conference for what is considered the first computer, the Electronic Numerical Integrator and Calculator (ENIAC), was held at the University of Pennsylvania on February 1, 1946. The machine (shown here with a technician) took up an entire room, weighed 30 tons and used more than 18,000 vacuum tubes to perform functions such as counting to 5,000 in one second. ENIAC, costing $450,000, was designed by the U.S. Army during World War II to make artillery calculations. The development of ENIAC paved the way for modern computer technology–but even today’s average calculator possesses more computing power than ENIAC did.

The first ever computer in Latvia was developed and made at the start-up Institute of Electronics and Computer Science in early sixties. No computers were made industrially in USSR at that time. Therefore successful completion of that project certainly represented a significant achievement. Built on a lot of vacuum tubes, the computer actually worked well and was used for supporting research activities for several years till the time when it became possible to replace it by a more powerful industrially made computer.
The CSIRAC was Australia’s first computer. The name stands for CSIR originally stood for “Council for Scientific and Industrial Research”. This name was in effect from 1926 to 1949.
A man and woman working at a Ferranti Pegasus computer. This computer was a classic 1950s/1960s mainframe installation, taking up the majority of space in a room.
The computer history at NTNU is much older than the computer departments. The very first computer at NTNU was called DIANA, or DIfferential ANAlysator. This was an analog electronic computer built by Jens Glad Balchen and the Division of Cybernetics in the years between 1952 and 1955.
Amdahl Corporation, Sunnyvale, CA. A computer manufacturer founded in 1970 by Dr. Gene Amdahl, chief architect of the IBM System/360. In 1975, Amdahl installed its first IBM-compatible mainframe, the 470/V6. In 1979, Amdahl left the company he founded to form Trilogy, which tried without success to make the world’s largest chip based on wafer scale integration.
First ever apple computer running windows. This is an Apple II with a monochrome screen and PC emulator hardware installed. The board was called the 88 Card, “the only fully functional 8088 processor for the Apple II personcal computer.
First hard disk The rotating drum technology allowed ERA to deliver the world’s first production stored-program computer (ATLAS – ERA 1101) to a customer site in October 1950. The engineers making the installation delivery to the National Security Agency predecessor were Frank Mullaney and Jack Hill. As shown in the photo below, these drum products came in various sizes. They were first used in several classified processors, then in the early 1100 computer series and the UNIVAC SS-80 and SS-90 computers. Dr. Cohen and Sid Rubens are credited with patenting the rotating magnetic drum. The drum development engineers and management shown in this early 50’s photo, left to right are: William Keye, Arnold Hendrickson, Robert Perking, Frank Mullaney, Dr. Arnold Cohen, and John ‘Jack’ Hill.

IBM 701. IBM’s first computer. Introduced in 1952, the 701 was designed for scientific work and research, which later led to the development of the high-level FORTRAN language. Nineteen machines were built, a record volume for such a machine in that era. Its internal memory contained 2,048 36-bit words of electrostatic memory and 8,192 words of magnetic drum memory (see early memories). It used magnetic tapes for storage and was one of the first machines to use plastic-based tapes instead of metal tapes. See IBM 650 and IBM 1401. At General Electric’s Aircraft Jet Engine Plant in Evendale, Ohio, this 1954 photo shows GE manager Herbert Grosch explaining the 701 to Ronald Reagan. Reagan was a TV personality for GE at the time.
