Dave Farquhar Retro Computing March 4, 2026March 4, 2026

The Homebrew Computer Club was a legendary early computer hobbyist group in Menlo Park, California. The book Fire in the Valley and the 1999 movie Pirates of Silicon Valley describe the group’s pivotal role in the computer industry. Its first meeting was 51 years ago this week, on March 5, 1975.

Intel 486DX2 CPU

Dave Farquhar Retro Computing March 3, 2026March 3, 2026

The Intel 486DX2, introduced March 3, 1992, was the first clock-multiplied x86 CPU. It was a clock-doubled version of the earlier 486 CPU. A DX2 ran at speeds of 50 or 66 MHz, using a 25 or 33 MHz front side bus. It was pin-compatible with the earlier 486 CPUs, using the same 168-pin socket, but the use of a clock multiplier let it run at double the clock rate, yielding a 50-70 percent speed improvement over running the CPU at the bus speed. Much of the speed gain came from taking advantage of the 486’s on-die 8KB L1 cache.

The 50-MHz Intel486 DX2 cost $550 each in 1,000-pieces quantities at the time of introduction.

AMD Am386 released March 2, 1991

Dave Farquhar Retro Computing March 2, 2026January 4, 2026

There is a popular misconception that AMD wasn’t good at cloning Intel CPUs. This is largely based on the observation that Intel released its 386 CPU in 1985, and AMD didn’t counter with its Am386 clone until March 2, 1991, nearly six years later. In this blog post, we will explore what took AMD so long, and how that delay played into future AMD CPUs.

What happened to GEM?

Dave Farquhar Retro Computing February 27, 2026April 27, 2026

GEM was an early GUI for the IBM PC and compatibles and, later, the Atari ST, developed by Digital Research, the developers of CP/M and, later, DR-DOS. (Digital Equipment Corporation was a different company.) So what was it, and what happened to GEM?

It was very similar to the Apple Lisa, and Apple saw it as a Lisa/Macintosh ripoff and threatened to sue. While elements of GEM did indeed resemble the Lisa, Digital Research actually hired several developers from Xerox PARC.

DRI demonstrated the 8086 version of GEM at COMDEX in 1984, and shipped it on 28 February 1985, beating Windows 1.0 to market by nearly 9 months.

Pentium III launched Feb 28, 1999

Dave Farquhar Retro Computing February 26, 2026February 26, 2026

26 years ago this week the Pentium III launched. It was noteworthy for being the CPU that broke the gigahertz barrier, but also for being a better chip than its successor. The Pentium 4 clocked higher, but a Pentium III at 1.13 GHz outperformed a Pentium 4 at 1.5 GHz. It wasn’t really until the Pentium 4 doubled the speed of the Pentium III that the P4 became a good CPU.

History of Dell computers

Dave Farquhar Retro Computing February 23, 2026February 23, 2026

The history of Dell computers is a classic story of how a little guy took on a titan of business and ended up becoming a titan himself, the kind of story Americans love to tell. Like many computer industry stories, it started with humble beginnings.

Michael Dell wasn’t a total rags to riches story. He wasn’t a pauper. He was the son of an orthodontist and a stockbroker, and showed an entrepreneurial bent starting at age 9, when he made $2,000 selling collectible stamps. As a teenager, he earned $18,000 selling newspaper subscriptions to an untapped market he found himself. Crucially, by the age of 15, he was showing an interest in computers. His parents wanted him to become a doctor.

Fifteen years ago, Twitter was still relevant. And nobody had ever tweeted from a Commodore VIC-20, the best selling computer of 1982, before. Syd Bolton, the curator of the Canadian Personal Computer Museum, decided to fix that. And on February 20, 2010, a VIC-20 tweeted.

Office Space released Feb. 19, 1999

Dave Farquhar Careers, Retro Computing February 19, 2026February 16, 2026

The classic black comedy Office Space debuted in theaters February 19, 1999. It was Mike Judge’s first live-action film. Judge is better known for his animated series Beavis and Butt-Head and King of the Hill, but I’ll argue Office Space shows Judge’s versatility, and for me, Office Space will always be his masterpiece.
