Computer History 1988
Apple cofounder Steve Jobs, who left
Apple to form his own company, unveiled the NeXT. The computer he
created failed but was recognized as an important innovation. At a base
price of $6,500, the NeXT ran too slowly to be popular.The significance of the NeXT rested in its place as the first personal computer to incorporate a drive for an optical storage disk, a built-in digital signal processor that allowed voice recognition, and object-oriented languages to simplify programming. The NeXT offered Motorola 68030 microprocessors, 8 megabytes of RAM, and a 256-megabyte read/write optical disk storage.

IBM introduced its PS/2 machines, which
made the 3 1/2-inch floppy disk drive and video graphics array standard
for IBM computers. The first IBMs to include Intel´s 80386 chip, the
company had shipped more than 1 million units by the end of the year.
IBM released a new operating system, OS/2, at the same time, allowing
the use of a mouse with IBMs for the first time.Tag :

Daniel Hillis of Thinking Machines Corp.
moved artificial intelligence a step forward when he developed the
controversial concept of massive parallelism in the Connection Machine.
The machine used up to 65,536 processors and could complete several
billion operations per second. Each processor had its own small memory
linked with others through a flexible network that users could alter by
reprogramming rather than rewiring.The machine´s system of connections and switches let processors broadcast information and requests for help to other processors in a simulation of brainlike associative recall. Using this system, the machine could work faster than any other at the time on a problem that could be parceled out among the many processors.

The Amiga 1000 is released. Commodore’s
Amiga 1000 sold for $1,295 dollars (without monitor) and had audio and
video capabilities beyond those found in most other personal computers.
It developed a very loyal following and add-on components allowed it to
be upgraded easily. The inside of the case is engraved with the
signatures of the Amiga designers, including Jay Miner as well as the
paw print of his dog Mitchy.Tag :

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´s commercial played on the theme of George Orwell´s "1984" and featured the destruction of Big Brother with the power of personal computing found in a Macintosh. Applications that came as part of the package included MacPaint, which made use of the mouse, and MacWrite, which demonstrated WYSIWYG (What You See Is What You Get) word processing.

Apple introduced its Lisa. The first
personal computer with a graphical user interface, its development was
central in the move to such systems for personal computers. The Lisa´s
sloth and high price ($10,000) led to its ultimate failure.The Lisa ran on a Motorola 68000 microprocessor and came equipped with 1 megabyte of RAM, a 12-inch black-and-white monitor, dual 5 1/4-inch floppy disk drives and a 5 megabyte Profile hard drive. The Xerox Star — which included a system called Smalltalk that involved a mouse, windows, and pop-up menus — inspired the Lisa´s designers.

Commodore introduces the Commodore 64.
The C64, as it was better known, sold for $595, came with 64KB of RAM
and featured impressive graphics. Thousands of software titles were
released over the lifespan of the C64. By the time the C64 was
discontinued in 1993, it had sold more than 22 million units and is
recognized by the 2006 Guinness Book of World Records as the greatest
selling single computer model of all time.Tag :

IBM introduced its PC, igniting a fast
growth of the personal computer market. The first PC ran on a 4.77 MHz
Intel 8088 microprocessor and used Microsoft´s MS-DOS operating system.
Adam Osborne completed the first portable
computer, the Osborne I, which weighed 24 pounds and cost $1,795. The
price made the machine especially attractive, as it included software
worth about $1,500. The machine featured a 5-inch display, 64 kilobytes
of memory, a modem, and two 5 1/4-inch floppy disk drives.
In April 1981, Byte Magazine Editor in Chief Chris Morgan mentioned the Osborne I in an article on "Future Trends in Personal Computing." He wrote: "I recently had an opportunity to see the Osborne I in action. I was impressed with it´s compactness: it will fit under an airplane seat. (Adam Osborne is currently seeking approval from the FAA to operate the unit on board a plane.) One quibble: the screen may be too small for some people´s taste."

Atari introduces the Model 400 and 800
Computer. Shortly after delivery of the Atari VCS game console, 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. Both sold well, though they had technical and marketing
problems, and faced strong competition from the Apple II, Commodore PET,
and TRS-80 computers.

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.
The 6502 microprocessor in the white package sits on the lower right.
About 200 of the machines sold before the company announced the Apple II
as a complete computer.
Computer History 1975
The January edition of Popular
Electronics featured the Altair 8800 computer kit, based on Intel´s 8080
microprocessor, on its cover. Within weeks of the computer´s debut,
customers inundated the manufacturing company, MITS, with orders. Bill
Gates and Paul Allen licensed BASIC as the software language for the
Altair. Ed Roberts invented the 8800 — which sold for $297, or $395
with a case — and coined the term "personal computer." The machine came
with 256 bytes of memory (expandable to 64K) and an open 100-line bus
structure that evolved into the S-100 standard. In 1977, MITS sold out
to Pertec, which continued producing Altairs through 1978.
The visual display module (VDM)
prototype, designed in 1975 by Lee Felsenstein, marked the first
implementation of a memory-mapped alphanumeric video display for
personal computers. Introduced at the Altair Convention in Albuquerque
in March 1976, the visual display module allowed use of personal
computers for interactive games.

Researchers at the Xerox Palo Alto
Research Center designed the Alto — the first work station with a
built-in mouse for input. The Alto stored several files simultaneously
in windows, offered menus and icons, and could link to a local area
network. Although Xerox never sold the Alto commercially, it gave a
number of them to universities. Engineers later incorporated its
features into work stations and personal computers.Tag :

The TV Typewriter, designed by Don
Lancaster, provided the first display of alphanumeric information on an
ordinary television set. It used $120 worth of electronics components,
as outlined in the September 1973 issue of Radio Electronics. The
original design included two memory boards and could generate and store
512 characters as 16 lines of 32 characters. A 90-minute cassette tape
provided supplementary storage for about 100 pages of text.Tag :

Hewlett-Packard announced the HP-35 as "a fast, extremely accurate electronic slide rule"
with a solid-state memory similar to that of a computer. The HP-35
distinguished itself from its competitors by its ability to perform a
broad variety of logarithmic and trigonometric functions, to store more
intermediate solutions for later use, and to accept and display entries
in a form similar to standard scientific notation.

The Kenbak-1, the first personal
computer, advertised for $750 in Scientific American. Designed by John
V. Blankenbaker using standard medium-scale and small-scale integrated
circuits, the Kenbak-1 relied on switches for input and lights for
output from its 256-byte memory. In 1973, after selling only 40
machines, Kenbak Corp. closed its doors.

The
Department of Defense Advanced Research Projects Agency contracted with
the University of Illinois to build a large parallel processing
computer, the ILLIAC IV, which did not operate until 1972 at NASA´s Ames
Research Center. The first large-scale array computer, the ILLIAC IV
achieved a computation speed of 200 million instructions per second,
about 300 million operations per second, and 1 billion bits per second
of I/O transfer via a unique combination of parallel architecture and
the overlapping or "pipe-lining" structure of its 64 processing
elements.This photograph shows one of the ILLIAC´s 13 Burroughs disks, the debugging computer, the central unit, and the processing unit cabinet with a processing element.

Digital
Equipment Corp. introduced the PDP-8, the first commercially successful
minicomputer. The PDP-8 sold for $18,000, one-fifth the price of a
small IBM 360 mainframe. The speed, small size, and reasonable cost
enabled the PDP-8 to go into thousands of manufacturing plants, small
businesses, and scientific laboratories.

IBM
announced the System/360, a family of six mutually compatible computers
and 40 peripherals that could work together. The initial investment of
$5 billion was quickly returned as orders for the system climbed to
1,000 per month within two years. At the time IBM released the
System/360, the company was making a transition from discrete
transistors to integrated circuits, and its major source of revenue
moved from punched-card equipment to electronic computer systems.
