Retro Computing

I saw an interesting perspective this week on the hobby of collecting retro games, from another retro enthusiast. Prices on retro games, he observes, are increasing. That’s making him ask a tough question: Is collecting retro games worth it?

Any hobby seems like a waste of time to the right (or wrong) person. If a hobby, such as collecting retro games, helps you to unwind and get focused, and you can get some of your money back out of it as you lose interest or approach end of life, then I have to argue that hobby is worth it.

The Compaq Presario 425 and 433 are popular machines with retro enthusiasts. They are Compaq 486s from 1993, and they look like exactly what they are. They’re well built, have recognizable branding, and don’t take up a lot of space. In some ways they’re the ideal 486 today. Let’s look at why they weren’t necessarily the ideal 486 for 1993, but they, along with the rest of the Presario line, helped transform Compaq anyway.

Cyrix was a scrappy, up and coming CPU manufacturer in the 1990s. They never had Intel’s name recognition, but for a few years they made life more difficult for its larger rivals, Intel and AMD. For a while, Cyrix processor chips were a popular choice for value-conscious PC buyers.

Cyrix contributed a lot of confusing alphabet soup to the 1990s CPU market, and their chips usually weren’t the highest-performing chips available. But they usually did provide good value for the money, even though Cyrix never was a premium brand.

I heard earlier this year that you can retrobright without chemicals, using only sunlight. I haven’t heard of a lot of people trying it. But I had a yellowed disk drive, and it’s summertime, so I decided to give it a shot.

A few people experimented with retrobright without chemicals in 2019, then the idea kind of faded away. I decided to try it, and found it works surprisingly well.

The Amstrad PC1512 and PC1640 were inexpensive Korean-made PCs that took Europe by storm in the mid 1980s. Amstrad was the UK’s largest computer maker, and it hoped to replicate that success in the United States as well. Here’s an overview of those machines, and why that effort was less than an overwhelming success.

My roundup of Commodore motherboards turned up on a vintage computer discussion board. A minor aside that I mentioned in passing turned into a major topic of discussion. And then the conversation turned in an entirely different direction. What about going with an FPGA solution, rather than vintage hardware? With an FPGA approach you can be certain you’re getting what you want. But what are the drawbacks of FPGA vs retro hardware, if any?

A purist will object to modern FPGA approaches, usually for more than one reason. But there can be practical advantages to an FPGA solution, and it’s also possible to blend it with a more traditional approach.

Someone asked in a vintage computer forum recently what the correct monitor would be to use with a VIC-20. Commodore never sold a white monitor the same color as the VIC. Its first color monitor was the 1701, which matched the C-64. If you want a period correct Commodore VIC-20 monitor, you have a couple of options. If you want a holy grail story, the matching monitor for the VIC-20 is a good one.

Commodore cancelled the VIC-1510 monitor for the VIC-20. But there were some third party monitors from the 1980s that look the part.

When I was a kid, computer science textbooks taught a language called Basic. They explained various commands, including POKE, which changed values in memory, or on a chip register. The books went out of their way to explain that you can’t harm a computer with a command, even a POKE. But it turned out there was an exception–the infamous POKE 59458,62 on the Commodore PET. The infamous killer POKE.

The killer POKE, POKE 59458,62, sped up the Commodore PET 2001’s video output at the expense of degrading the video quality. The tradeoff seemed worth it, except it could damage the machine over time.
