Why people say CRTs don’t have pixels

Dave Farquhar Retro Computing May 29, 2026November 27, 2025 1 Comment

I keep hearing people say that CRTs don’t have pixels. That is incorrect. We talked about pixels all the time in the 1980s when CRTs were all we had. In this blog post, I will try to clear up the confusion around pixels and the difference in the way CRTs and LCDs handle them.

DR DOS: Revenge of CP/M

Dave Farquhar Retro Computing May 29, 2026May 29, 2026 3 Comments

DR DOS was a third party clone of MS DOS that developed a well-deserved niche following in the late 1980s and early 1990s. Even though it was first released May 28, 1988, its copyright date of 1976 suggests some historical significance. Indeed, it was more than just any clone of MS-DOS. Arguably it was both a clone and a predecessor. DR DOS was its own grandpa.

AMD K6-2 released May 28, 1998

Dave Farquhar Retro Computing May 27, 2026May 27, 2026 0 Comment

AMD launched its K6-2 microprocessor on May 28, 1998, a little over a year after its predecessor, the K6. The K6-2 built upon the K6, increasing performance to better compete with the Pentium II. Since it still used the Socket 7 architecture, a complete system based on the K6-2 could be quite a bit cheaper than an equivalent Pentium II system.

Bill Gates’ Internet Tidal Wave Microsoft memo

Dave Farquhar Retro Computing May 27, 2026May 27, 2026 1 Comment

30 years ago today, on May 26, 1995, Bill Gates wrote a company memo to Microsoft. It was something he did every few years, outlining the company’s top priority. But this one was different. It was a five-alarm fire titled “The Internet Tidal Wave,” warning that the Internet was going to change everything and had the potential to disrupt the current order, displacing Microsoft and other titans of the computer industry.

What happened to Tandy computers

Dave Farquhar Retro Computing May 26, 2026December 1, 2025 2 Comments

What happened to Tandy computers? Tandy was a pioneer in the personal computer industry, one of three companies that introduced pre-built, ready to run computers in 1977. And for about 12 years, they were a force to be reckoned with. But depending on how you count it, it came to an end in 1993 or 1995. Here’s what happened to Tandy computers and why they fell so quickly.

In 1989, the Tandy 1000 was still the best selling computer in the world but it was no longer profitable and sales were fading fast. Turnaround efforts failed and on May 26, 1993, Tandy sold its manufacturing operations to AST, another maker of PC clones.

Quantum Link: AOL before it was AOL

Dave Farquhar Retro Computing May 25, 2026May 25, 2026 3 Comments

I used AOL before it was AOL. And if you had a Commodore and a modem in the 1980s, you may have too. On May 24, 1985, Control Video reorganized and became Quantumlink, or Q-Link for short, on its way to reinventing itself as an online service for home computers. It opened for business November 5 of the same year.

Advantages and disadvantages of Windows 3.0

Dave Farquhar Retro Computing May 22, 2026May 22, 2026 0 Comment

I hear the question from time to time what the advantages and disadvantages of Windows 3.0 were. Windows 3.0, released May 22, 1990, is generally considered the first usable version of Microsoft Windows. It was certainly the first one to see commercial success. The oft-repeated advice to always wait for Microsoft’s version 3 is a direct reference to Windows 3.0 that still gets repeated today.

Although Windows 3.0 is clumsy by today’s standards, in 1990 it had the right combination of everything to take the world by storm.

Microsoft’s attempted merger with Intuit

Dave Farquhar Retro Computing May 21, 2026May 21, 2026 3 Comments

Before Microsoft was obsessed with Netscape, it was obsessed with another piece of software: Quicken. Unable to beat it in the marketplace with a clone called Microsoft Money, Microsoft tried to buy its publisher, Intuit, outright. On May 20, 1995, Microsoft and Intuit abandoned that merger over antitrust concerns.

On May 20, 1982, Kaypro shipped its very successful Kaypro II computer, a portable computer that ran CP/M and its associated software. Its main innovation was bundling a selection of popular software with the computer and selling the bundle for less than the combined suggested retail price of the software.

Microsoft Antitrust case of 1998

Dave Farquhar Retro Computing May 19, 2026May 19, 2026 1 Comment

On May 18, 1998, the Department of Justice filed an antitrust lawsuit against Microsoft, seeking ultimately to break up the company. The case was controversial at the time and remains controversial now, but I would also argue the case is misunderstood today, and the Microsoft of today is not the Microsoft of the 1990s, and the Microsoft Antitrust Case of 1998 had something to do with that.

It’s popular to say today that the Microsoft antitrust case of 1998 was unnecessary and the market figured out how to handle Microsoft. But provisions in the settlement kept Microsoft from behaving toward Google the way they behaved toward Netscape and Lotus.
