Big Blue birthday: IBM PC turns 20

By Jim Battey


(IDG) — The IBM PC was introduced to the world 20 years ago at
a press conference in New York on August 12, 1981. Evolving from the
MITS Altair hobbyist computer and taking cues from early PCs such as
the Apple II, the IBM PC — and the story behind its development —
provided a foretaste of how the whole tech industry took shape.

The IBM PC originated not at Big Blue’s Armonk, New York,
headquarters but at its small Entry Systems Division in Boca Raton,
Florida, which was headed by IBM veteran Bill Lowe. It was Lowe who
proposed to IBM’s top brass that they build a personal computer made
of components provided by outsiders, bucking IBM’s long-standing
practice of using its own hardware and software.

A one-year deadline was established that would have been impossible
to meet operating under IBM’s traditionally proprietary ways. Lowe
says IBM’s decision to buy instead of build was driven by economics.
"We visited retail stores such as Sears and ComputerLand and
determined that the PC had to be distributed through retail for us to
make a profit," Lowe says, emphasizing that it would have been
too expensive to market the PC through IBM’s own sales force.

Lowe says the proposal to sell the PC through retail channels led
to the decision to go with an open architecture. "Distributors
would have to service the product themselves and retailers would
accommodate the product only if we used non-IBM hardware," he

One IBM engineer involved in the development of the PC, Dave
Bradley, thinks this decision changed the face of the industry.
"By going with an open system you invite the rest of the industry
to participate. For example, other companies such as Lotus were able
to develop applications," Bradley says. This paved the way for
open hardware standards and, eventually, the opportunity for thousands
of companies in the PC sector.

Intel was one of the many companies that flourished. IBM selected
Intel’s 8088 processor for the system chiefly because it was the only
16-bit processor available that had an 8-bit bus. Also, Bradley says,
"We were familiar with the Intel processing family, having worked
with them on the Datamaster," which was the forerunner to the IBM

Another company that benefited from the open system was Microsoft.
In the early 1980s the most common OS in non-Apple PCs was CP/M,
developed by Digital Research in Pacific Grove, California. "We
sent a team to the West Coast to meet with [Digital Research], but
they weren’t interested in working with us," Lowe says.

Microsoft, then a small software company in Bellevue, Washington,
seized on this opportunity. Co-founders Bill Gates and Paul Allen
assured IBM that in addition to developing the Basic programming
language for the IBM PC, Microsoft could provide an operating system.

But Microsoft did not have an OS of its own. Racing against IBM’s
tight deadline, Allen got in touch with a local hardware vendor that
did have an OS, Seattle Computer Products.

Microsoft executive Jeff Raikes remembers what the industry was
like when he joined the company in 1981. "The software business
was dominated by hardware companies, and everybody thought they would
just come in and wipe us out," Raikes says. "People forget
that Microsoft took a huge bet to think that an independent operating
system and programming language would be successful."

Lowe says the selection of Microsoft was due, in part, to its
ability to meet the deadline. "We put a real premium on schedule.
They were able to provide an operating system on the schedule we
needed," he says.

After shipping in October 1981, the roaring success of the IBM PC
meant that PCs were ready to make the leap onto corporate desktops.
"IBM legitimized the notion of the PC — that it would not be
just a hobbyist computer," Raikes says.

Soon IBM compatibles from Compaq and software applications such as
Lotus 1-2-3 appeared, and the PC industry shifted into full gear.
Summarizing the success of the IBM PC, Bradley says, "Clearly it
was a product whose time had arrived."

Predictions for 2010

TERABYTES OF STORAGE: A media-rich future means a heavy-storage
future. The 1.44MB floppy might survive longer than we think, but by
2010 the traditional floppy, superfloppies such as the Zip, and even
CD burners will disappear as DVD burners become stock items. And
multigigabyte hard drives will go by the wayside as multiterabyte
drives will be required to hold the Microsoft bloatware of a decade

64-BIT CPU UNDER THE HOOD: The typical configuration of today’s PC
includes a 32-bit processor running at 1.0GHz or faster, 128MB of RAM,
and 128KB of Level 2 cache. A limited number of of 64-bit desktop PCs
also are expected to ship in 2001, following the delivery of Intel’s
64-bit Itanium processor. In 10 years, we’ll all be using 64-bit
systems with 64GB or more of RAM and several megabytes of cache to
process the voice and video streaming throughout the corporate

NO-HANDS INPUT: Ten years out, everyone will be using a flat-panel
screen, typically 18 inches diagonally, but it will sport a built-in
digital camera for full-motion videoconferencing. Keyboards and mice
will be wireless, and they’ll incorporate fingerprint readers for
authorizing the user. And these input methods will be supplemented by
speech recognition, which, along with biometric security, will be
built into the OS of future. This OS will be either a Windows
derivative or a Mac/Linux fusion, depending on your personal degree of

WIRELESS CONNECTIONS: In the future, Bluetooth and 802.11 wireless
LANs will have evolved into something that is secure. It is difficult
to foresee whether or not wireless LANs will scale to gigabit speeds,
which we deem a prerequisite for secure on-demand video applications.
For Net access, there will still be a battle between DSL and cable
