William C. Lowe, Personal Computing Pioneer

November 8, 2013

As my own personal experience shows, and as others will attest, large manufacturing corporations are not innovators. They enjoy the status quo, and they prefer incremental improvements of their products over new products. Some make up for this shortcoming by acquiring smaller companies with innovative products, while others diminish over time and finally cease to exist. The current corporate mindset is that R&D is an expense, not an investment.

Imagine management's feedback at the meeting where an employee of a toothbrush manufacturer first suggested an electric toothbrush. "We're making enough money with our current toothbrushes. They're easy to manufacture, so our profit margin is high. Are people so lazy they can't brush their own teeth? Who wants to replace batteries, and everybody knows that electricity and water is a deadly combination."

William C. Lowe, who died on October 19, 2013, at age 72,[1-5] may have faced a similar grilling in 1980 while he worked to convince IBM to develop and market a personal computer. His approach was antithetical to his employer's business strategy. Foremost, IBM was a manufacturer of "big iron," the common term for mainframe computers of that era, and a personal computer was a very small chunk of steel.

IBM's products were built in a vertically integrated environment, where even some nuts and bolts might be manufactured in-house, and Lowe's proposed computer would be built from components not manufactured by IBM. As a further insult to management, even the operating system software would come from elsewhere; and software, then as today, has a huge profit margin. This software decision led to the long term hegemony of Microsoft in the personal computer business, as explained below.

William Cleland Lowe was born in Easton, Pennsylvania, on January 15, 1941, and he attended nearby Lafayette College, graduating with a Bachelor of Science degree in physics.[1-3] Immediately after college, Lowe joined IBM in 1962 as a product test engineer in Endicott, New York. Lowe rose quickly through the IBM ranks, being named director of development and manufacturing operations for the General Systems Division in Atlanta, Georgia, in 1975.[1]

Lowe was director of the IBM Boca Raton Labs in 1980 shortly after personal computers from Apple, Commodore, and Atari had entered the market.[3] There are reports at that time of Atari's proposing to manufacture a computer that IBM would sell; or, that IBM might acquire Atari for this purpose. There are also reports that Lowe had presented the Atari scenario to IBM management, only to be told that it was "the dumbest thing we've ever heard of."[3]

Not surprisingly, IBM management thought that IBM should launch a personal computer of its own manufacture, and it should do this quickly. This meant stepping away from "Big Blue's" typical multi-year, vertically-integrated development cycle in which everything was done in-house.[2] IBM's CEO at the time, Frank T. Cary, instructed Lowe to bring an IBM personal computer to market within a year, so Lowe assembled a team of twelve engineers, called "The Dirty Dozen," for this effort, code named, "Project Chess."[3] The only way this could be accomplished would be through use of third-party hardware and software.[4]

The electronic hardware was easy to obtain, but the operating system software was another matter. At that time, Digital Research had a highly popular operating system, CP/M; and Microsoft sold application software, including a Basic computer language interpreter coauthored by Bill Gates, himself, that ran under CP/M.[4] Microsoft was happy to team with IBM under the conditions set; but, Digital Research was a successful company in its own right, and it was leery of the conditions in IBM's non-disclosure agreement.[4]

IBM went back to Microsoft, and Bill Gates devised a plan whereby Microsoft would acquire an operating system, QDOS (Quick and Dirty Operating System), from Seattle Computer Products and modify it for IBM's needs. This operating system became IBM PC DOS, and it was also sold by Microsoft as MS-DOS after a few years.[4]

The IBM Model 5150 Personal Computer was introduced on August 12, 1981, at $1,565 ($3,900 in today's money), not including a monitor.[2-3] Its hardware included an Intel 4.77MHz 8088 microprocessor, 16 kilobytes of RAM (expandable to 256K), and it could be purchased at Sears.[3] Lowe had expected to sell 220,000 units in a three-year period, but actual sales were six times this figure in just the first year.[3-4] The 220,000 unit estimate was actually larger than the entire installed base of all IBM computers at the time.[3]

The real winners in all this were Intel and Microsoft. Since IBM had acquired its PC components from third-parties, there was soon a plethora of "PC-compatible" computers, all of which used the Intel CPU chip and MS-DOS. These computers were less expensive and often included hardware features not on IBM machines. One hurdle in all this was IBM's copyright on the BIOS ROM, which contained the code to interface the hardware with software. The BIOS code was easily "reverse-engineered."

Lowe became vice president of IBM's System Products Division (White Plains, New York) in 1982, and then its president, in March 1985. He was elected an IBM corporate vice president in January 1986.[1] IBM introduced its PS/2 computer in 1987, hoping to regain market share with an improved operating system called OS/2, which was ironically coded in partnership with Microsoft.[4] Lowe left IBM for Xerox in 1988, reportedly because of better opportunity with Xerox rather than problems with IBM.[2] Lowe eventually became CEO of Gulfstream Aerospace in 1991.[3]
