Where to buy vintage computers

Collecting vintage computers can be fun. I also personally think it’s great that people are interested in preserving that history. Where to buy vintage computers hasn’t changed much over the years. It just may take a bit more work than it used to.

Some people think old computers are priceless. Others think they’re worthless. I don’t recommend wasting your time with people who think a Dell Pentium III laptop is worth $300. Think of the times you found a jewel for five bucks and keep moving.

The IBM PS/1 (or IBM PS1)

The IBM PS/1, sometimes called the IBM PS1, was a line of 1990s personal computer systems, not to be confused with the Sony Playstation video game console that’s also often called the PS1. The PS/1 was IBM’s second attempt at a mass market consumer PC, after the ill-fated PCjr.

You can neatly divide the PS/1 into two generations. While they ran the same software, they had major philosophical differences. Perhaps more than any other computer line, they represent IBM’s change of heart in the early 1990s as it tried to survive in an extremely competitive and crowded market.

Cleaning N64 game cartridges

Dave Farquhar Retro Computing June 23, 2017March 28, 2023

Cleaning N64 game cartridges is a controversial topic. It doesn’t have to be. There are some techniques floating around that can be harmful. But I also bristle when I see people say there’s one and only one right way. Here are some techniques for cleaning N64 game cartridges, based on my decades of experience fixing computers and game systems.

Computers in 1985: It was a very good year

Dave Farquhar Retro Computing June 22, 2017December 28, 2024

In some ways, 1985 was a really pivotal year for computing. The industry was changing fast, but in 1985, many relics from the past were still present even as we had an eye for the future. Here’s a look back at computers in 1985 and what made that year so interesting.

I think 1985 was interesting in and of itself, but it also made the succeeding years a lot more interesting. A surprising amount of the technology that first appeared in 1985 still has an impact today.

What happened to Digital Equipment Corporation?

Dave Farquhar Retro Computing June 20, 2017October 3, 2018

Digital Equipment Corporation was perhaps the second most important computer company in history, behind IBM. Its minicomputers challenged IBM, and, indeed, Unix first ran on a DEC PDP-7. DEC’s Alpha CPU was one of the few chips to make Intel nervous for its x86 line. It created the first really good Internet search engine. In a just and perfect world, DEC would still be dominating. Instead, it faded away in the 1990s. What happened to Digital Equipment Corporation, or DEC?

There’s a short answer and a long answer.

What is a game cartridge?

What is a game cartridge? If you’re asking, you must not have grown up in the 1980s. But that’s OK. We’re happy to share our generation’s fun with you.

A game cartridge is a plastic case containing a circuit board, a connector, and a ROM chip. CDs and DVDs ultimately displaced them because they offered higher capacity at a lower cost. But in the 1970s and 1980s, the only lasers our game consoles had were the ones they drew on the screens in games about aliens. We liked our cartridges, even if we called them tapes sometimes.

Commodore 64 models

Over the course of its 12 years on the market, Commodore released a number of Commodore 64 models. The computer’s capability changed very little over time, but the technology did. The world changed a lot between 1982 and 1994, and that gave Commodore some opportunities to lower costs, chase other market segments, or both.

Here’s an overview of the various Commodore 64 models that hit the market over the machine’s long life.

IBM PS/2 vs PC

The IBM PS/2 line was a fairly radical departure from the older IBM PC line. This was deliberate, as IBM wanted to disrupt the clone industry, which it saw as a threat to its business. Here’s a look back at the IBM PS/2 vs PC, the line it replaced.

IBM succeeded with the PC because it created an ecosystem, not just a PC. IBM’s misstep was creating an open architecture and then trying to close it back up after the fact with the PS/2. In IBM’s defense, it’s not clear whether they knew this at the time. If nothing else, in the case of the IBM PS/2 vs PC, IBM created a classic case study of open architecture vs closed.

Compaq Deskpro 386

Dave Farquhar Retro Computing June 7, 2017January 28, 2025

The Compaq Deskpro 386, announced in September 1986, was a landmark IBM PC compatible computer. The first fully 32-bit PC based on the Intel 386, its release took the leadership of the PC ecosystem away from IBM, and Compaq became the leader.

Compaq was no upstart by 1986. Its Compaq Portable was a runaway success earlier in the decade, and Compaq was a darling of the industry. The Deskpro 386 solidified Compaq’s position as an industry innovator.

Radio Shack computers

Radio Shack released one of the first home computers, the TRS-80 Model I, in 1977. Between 1977 and 1979, it sold 100,000 units. Radio Shack sold them just as quickly as Tandy could make them. You can count Radio Shack and its parent company Tandy among computer companies that failed, but they enjoyed a good run. For a time, Radio Shack computers, later marketed as Tandy computers, were very popular.

Radio Shack and Tandy computers included the TRS-80 Model I from the inaugural class of 1977, the pioneering Model 100 portable, and the Tandy 1000 series, which helped bring PC clones into homes.

There were several reasons why Radio Shack computers were hard to compete with in the late 1970s and throughout the 1980s.
