Texas Instruments 486SXL CPU

Dave Farquhar Retro Computing May 14, 2026May 14, 2026 0 Comment

On May 14, 1992, Texas Instruments licensed Cyrix‘s 486SLC and 486DLC technologies. The agreement allowed Cyrix to use Texas Instruments’ manufacturing facilities, and for TI to create derivative chips from Cyrix’s technology. In the end, TI didn’t make as many chips for Cyrix as SGS-Thomson or IBM did, but TI did end up making interesting derivatives of Cyrix’s CPUs, including the 486SXL-40, the fastest 386-class CPU ever made. But without the burst transfer feature that Intel and AMD 486s have, none of TI’s 486s ended up performing quite up to par with an Intel or AMD 486.

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.

On May 12, 2017, ransomware named Wannacry started spreading across the globe, infecting and encrypting Windows systems by exploiting CVE-2017-0144, a flaw that a two-month-old Microsoft patch, MS17-010, had fixed.

It quickly became one of the biggest Windows outbreaks ever. Why was it so bad, and what could have made it go better?

The consumer VCR turns 51 this week. On May 10, 1975, Sony introduced the Betamax. Although Betamax lost the famous format war, it kicked the door open, being the first VCR format that mere mortals could aspire to own and use.

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.

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.

Dave Farquhar Software May 6, 2026May 6, 2026 10 Comments

Before May 2013 there was always question about whether you actually owned software after you paid for it. But before May 6, 2013, you certainly had more control. That was the day Adobe switched to a subscription-only model for its creative software. Other companies followed suit, notably Microsoft with its office suite.

First desktop computer: Datapoint 2200

Dave Farquhar Retro Computing May 5, 2026May 5, 2026 1 Comment

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.

On May 4, 1984, Milton Bradley, a leading producer of board games for 124 years, agreed to sell itself to Hasbro. Changes in the way people played games in the 80s, especially kids, put pressure on the company. In this blog post, I’ll explain how changing times led Milton Bradley to make a transformational bet at the worst possible time that ultimately sunk the maker of the game Battleship, and what happened to what was left of Milton Bradley.

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

Dave Farquhar Retro Computing May 3, 2026 0 Comment

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.
