Dave Farquhar Retro Computing May 13, 2026May 13, 2026

Kevin O’Leary, who calls himself Mr. Wonderful, is one of the most divisive stars of the reality TV series Shark Tank. Like Mark Cuban, O’Leary made much of his fortune in technology. But while Cuban is a dotcom billionaire, O’Leary made his money through a different model, selling software at retail. In this blog post, we will map out how Mr. Wonderful became rich. May 13 is a happy anniversary for him, but I can think of a major toymaker who doesn’t call him Mr. Wonderful, and doesn’t think there’s much of anything wonderful about him at all.

Dave Farquhar Retro Computing May 8, 2026May 8, 2026

On May 8, 2006, corporate and straitlaced Dell completed its purchase of Alienware, a maker of edgy gaming computers. It was a long courtship. Dell considered buying Alienware for four years before making the deal. And the tie-up of this odd couple has worked. At the time of this writing, Dell has owned Alienware for 20 years, twice as long as it didn’t own it.

Dave Farquhar Retro Computing May 7, 2026May 7, 2026

29 years ago, on May 7, 1997, Intel introduced its Pentium II processor. It wasn’t the first followup to the very successful Pentium. But the Pentium II overcame problems with the Pentium Pro that kept it from gaining more widespread mainstream acceptance.

First desktop computer: Datapoint 2200

Dave Farquhar Retro Computing May 5, 2026May 5, 2026

The first desktop computer dates to earlier than you probably think. And officially at least, it was an accident. Great inventions often are. But it was surprisingly similar to desktop computers that followed it.

Design work on the first desktop computer commenced in 1969, and it hit the market in May 1970. Yes, you read that right. It predated the Apple II and even the Altair 8800 by several years, and the IBM Personal Computer and IBM compatibles by more than a decade. And it wasn’t built in Silicon Valley either. But this ahead-of-its-time oddball is the direct ancestor of your modern desktop or laptop computer, right down to the Intel processor design.

Microsoft’s open sourcing of 86-DOS and what it means

Dave Farquhar Retro Computing May 3, 2026

On April 28, 2026, Microsoft unexpectedly open sourced 86-DOS. This is the direct ancestor to PC DOS 1.0. I’ve written a number of things about the controversies around PC DOS 1.0 and early versions of MS-DOS, so of course I need to say something about this, even if I’m a few days late.

Why Commodore went bankrupt in 1994

Dave Farquhar Retro Computing April 30, 2026April 30, 2026

On April 29, 1994, Commodore announced it was bankrupt and was going out of business. Its demise was a long time coming. Arguably it had been inevitable for 10 years. But the reasons Commodore went bankrupt are often oversimplified and misunderstood.

What happened to Palm Pilots?

Dave Farquhar Retro Computing April 29, 2026April 29, 2026

Palm was a high-flying brand in the late 1990s, creating the first really popular personal data assistant. Then it seemed to vanish almost as quickly as it came. What happened to Palm Pilots, and the company who made them? On April 28, 2010, HP acquired Palm for $1.2 billion, with big plans to use its tech to compete directly with Apple. That didn’t go to plan, so you’re not reading this on a Palm-based phone or tablet. But the tech may be hiding in plain sight elsewhere in your home.

The TRS-80 Model 100 was an early laptop computer manufactured by Kyocera in Japan and marketed in North America by Radio Shack. Kyocera’s own version, the Kyotronic-85, didn’t set any sales records. But the TRS-80 Model 100 and the line it spawned proved widely successful in the United States.

How Xerox invented the GUI and lost it

Dave Farquhar Retro Computing April 27, 2026June 16, 2026

Xerox is a company that people who want to sound smart or to sound visionary should be familiar with. In the 1960s, Xerox was a company that seemed to own the future, in a position similar to the position Apple or Nvidia are in today. The Xerox name was synonymous with photocopying. In the days before digital document retrieval, every office had at least one photocopy machine. Xerox was in the enviable position of its trademark being a verb. If I said I was xeroxing, people knew exactly what I was doing. But Xerox famously invented the GUI and got very little for its invention.
