Rod Canion and Ben Rosen

Abstract

Rod Canion (born 1945) and two former Texas Instruments colleagues sketched a portable IBM-compatible computer on a placemat in a Houston pie shop in 1982, and built Compaq into the fastest-growing company in American history: $111 million in its first year, the Fortune 500 in four. Ben Rosen (1933–2026), a Morgan Stanley analyst turned venture capitalist, put up the first $1.5 million, chaired the board for eighteen years, and fired Canion in October 1991 when the company posted its first loss. Canion’s Compaq had beaten IBM to the 386 and taken the PC standard away from it; Rosen’s Compaq cut prices, bought Digital Equipment, and was sold to Hewlett-Packard in 2002. The clean-room BIOS and the standards war are in Compaq and the BIOS Clean Room; this is the story of the two men.

The Analyst

Benjamin Maurice Rosen was born in New Orleans on March 11, 1933, the son of a dentist, and took an engineering degree at Caltech in 1954, a master’s at Stanford in 1955, and, after years as an engineer at Raytheon and Sperry Gyroscope, an MBA from Columbia in 1961. He spent the next fifteen years on Wall Street, ending as Morgan Stanley’s senior technology analyst, and in the late 1970s he became the person the industry read: the Rosen Electronic Letter and his Personal Computer Forum conferences were where Wall Street learned what a microcomputer was and which companies would matter. He noticed Apple early. In 1981 he founded Sevin Rosen Funds with L. J. Sevin, the founder of Mostek, to invest in the companies he had been writing about; the newsletter passed to Esther Dyson, who bought the business in 1983 and renamed it EDventure. The firm’s first fund backed Lotus Development, whose 1-2-3 became the spreadsheet of the IBM PC, and a Houston start-up with no product.

The Placemat

Joseph Rodney Canion was born in Houston on January 19, 1945, took bachelor’s and master’s degrees in electrical engineering at the University of Houston in 1966 and 1968, and joined Texas Instruments, where he rose to senior management. In 1981 he and two TI colleagues, Jim Harris and Bill Murto, decided to leave and start something; the first idea was a Mexican restaurant, and the second a hard-disk business. What they settled on, over dinner at the House of Pies on Kirby Drive, was a portable computer that would run IBM PC software, and Ted Papajohn, an industrial designer they had brought along, drew it on the placemat. Compaq Computer Corporation was incorporated on February 16, 1982. Rosen’s firm put in $1.5 million, and Rosen became chairman.

The Compaq Portable was announced in November 1982 and shipped in March 1983 at $2,995: 28 pounds, a nine-inch screen, a fold-down keyboard, and a BIOS written by engineers who had never seen IBM’s, so that IBM could not sue. It sold 53,000 units in the first year for $111 million of revenue, the highest first-year sales of any American company to that date. Compaq reached the Fortune 500 in 1986, faster than anyone before it. Canion’s rule, which he repeated to every reporter, was compatibility above everything: a Compaq would run every program and every card an IBM PC would, and be built better.

The 386

IBM had launched the PC/AT in 1984 on the 80286 and was in no hurry to move. When Intel finished the 80386 in 1985, Canion decided Compaq would ship it first. The Deskpro 386 appeared in September 1986, seven months before IBM’s first 386 machine, and it settled a question the industry had been avoiding: whether “the standard” meant whatever IBM did or whatever ran IBM software. When IBM answered in April 1987 with the PS/2 and its proprietary Micro Channel bus, licensed for a fee, Canion organised the answer. In September 1988 nine clone makers, Compaq, Hewlett-Packard, AST, Epson, NEC, Olivetti, Tandy, Wyse and Zenith, the “Gang of Nine”, announced EISA, a 32-bit bus that stayed compatible with the old cards. Micro Channel died; the PC standard, from then on, belonged to no single company. Canion’s own account is his 2013 book Open: How Compaq Ended IBM’s PC Domination and Helped Invent Modern Computing.

October 1991

The premium that paid for Compaq’s engineering stopped being available in 1991. Clones assembled from the same Intel and Microsoft parts sold for hundreds of dollars less, Dell sold direct, and a recession did the rest. In the third quarter of 1991 Compaq posted its first loss, $71 million, and laid off 1,400 people, 12 percent of its staff. Rosen had already concluded that Canion’s engineers took too long and spent too much. He ran a small team in secret, outside the company’s normal process, to prove that a competitive low-cost PC could be built from off-the-shelf parts in months; it could. On October 25, 1991, after a board meeting that ran into the night, the directors voted Canion out and put Eckhard Pfeiffer, the chief operating officer, who had built Compaq’s business in Europe, in his place. About 150 employees stood outside headquarters with signs reading “We love you, Rod.” Canion turned down an offer to stay on the board. Harris resigned two weeks later.

Pfeiffer’s Compaq did what Rosen wanted: the ProLinea line of June 1992 sold desktops for under $900, the Presario of August 1993 took Compaq into retail stores, the company took the number-one position in PCs from IBM in 1994, and revenue rose from $3.3 billion in 1991 to $31 billion in 1998. The price war that followed is described in The Commodity PC. Then Pfeiffer bought Tandem for $3 billion in 1997 and Digital Equipment for $9.6 billion in 1998, and the integration failed. In April 1999 Rosen fired him too, ran the company himself as acting chief executive for four months, and installed Michael Capellas. Rosen retired as chairman in 2000; Capellas sold Compaq to Hewlett-Packard for about $25 billion in 2002. Rosen had chaired the company for eighteen years, longer than any of the three men who ran it under him.

Afterwards

Canion founded Insource Technology, an IT consultancy, in Houston in 1992 and chaired it for years; he backed Questia, an online library, in 1999, and sat on the boards of Houston technology companies. A 2016 documentary, Silicon Cowboys, retold the Compaq story with Canion, Harris and Murto on camera.

Rosen went back to investing, to Caltech, whose board of trustees he chaired from 2001 to 2005, and to a project with his brother Harold, the engineer behind the first geostationary communications satellite: Rosen Motors, which spent the mid-1990s building a hybrid car powered by a gas turbine and a flywheel and closed in 1997 when no manufacturer would take it. He received the IEEE Founders Medal in 1999. Ben Rosen died in New York on August 23, 2026, aged 93.
