Computer History 1987
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 :
