Jason Walsh takes a look back at Apple's largely
forgotten 16-bit home computing powerhouse, the Apple IIGS.
In the late 1980s and early 1990s, computing made a great leap
forward with the advent of 16-bit microcomputers like the Macintosh, Commodore Amiga, and
Atari
ST.
The Apple
II, introduced in 1978, was a phenomenally successful platform,
eventually coming to possess a 20% share of the personal computer
market in the US. But by 1985 the era of the 8-bit computers was coming
to an end.
While the Mac was running rings around the IBM PC - in terms of
usability if not sales - Apple decided on a different strategy to deal
with the 16-bit home computer market. The Apple IIGS, released in 1986, was Apple's answer to
Commodore's and Atari's next-generation machines.
As every Mac-fan knows, the Apple story
started in 1976 when two phone phreakers decided to make a computer.
The pair were both named Steve: Steve Wozniak was the visionary
engineer who designed the machine, soon to be called the Apple I, and
the now infamous Steve Jobs was the man who saw the commercial
potential of computers in the home.
Aside from troubling the phone company, the pair had legitimate
engineering jobs: Wozniak was working at Hewlett-Packard, and Jobs at
Atari.
It was in Jobs's garage that Wozniak designed the Apple I computer. After
offering it to HP, which turned it down, Apple Computer was formed to
sell the machine. It was marketed in 1976 at a price of $666. The Apple
I was the first single-board computer with a built-in video interface
and onboard ROM that told the machine how to load programs from an
external source.
Jobs was marketing the Apple I at hobbyists like members of the
Homebrew Computer Club, but when he and Woz sat down to design the
Apple
II, he had grander plans.
In 1977, Apple unveiled the Apple II to the world - the first
color-capable microcomputer. The company strongly encouraged
third-party software development, and by 1983 there was a library of
16,000 software programs for the machine. The Apple II set the standard
in personal computers and was an enormous success. Within three years
the company had made a profit of $139 million - 700% growth.
Apple went public in 1980 with an initial offering of $22 per share,
and the price went up to $29 on the first day of trading. At the end of
the first day, Apple had a value of $1.778 billion, the biggest initial
public offering since Ford. Jobs alone was worth $250 million.
Market Reception
By 1984, Apple's loyal users were hungry for a new machine. Despite
having been revised several times, the Apple II was showing its age,
while the Mac was
too expensive for home use - and while the Mac featured a
high-resolution display, it was monochrome.
When you consider that the Apple II was the first computer capable
of color graphics, there was no way the Apple II user-base would settle
for a mono machine.
In 1984, Apple had released
the Apple
IIc, but this was still an 8-bit computer. Its main selling point
was that it was portable. It had a tiny form factor, and Apple released
an LCD screen and battery pack for it, making it a very capable
"laptop". And for those on a budget, Apple offered a compact 9"
green-screen display
The IIc sold in very high quantities, but users were hungry for more
power. The planned successor was variously code named Cortland,
Phoenix, Rambo, Gumby, and Mark Twain.
To the acclaim of its fans, Apple unveiled the IIGS in September 1986. The machine was quite
pricey at $999 plus $399 for a 3.5" floppy drive or $299 for a 5.25"
drive. A colour monitor cost a further $499 - or $129 for a mono green
screen. Despite this, the IIGS
initially performed well, outselling the Mac at the time of launch.
This initial success was not to continue. Apple did not seriously
market the machine, and it was eventually outsold by the Amiga and the
Mac. Outside of North America, the machine made some impact in France,
but Apple's sky-high prices in comparison to those of Commodore and
Atari hampered the machine in Europe. An Amiga could be had for almost
half the price of a IIGS.
