Atari 2600 vs 7800

The Atari 2600 and 7800 are directly related. After the Atari 5200 flopped, Atari needed a better successor to take over for the aging 2600. So the Atari 2600 vs 7800 is a natural comparison. Let’s look at the improvements the 7800 had over its predecessor, and why it wasn’t able to match the 2600’s runaway success.

Commodore 1571 disk drive

The Commodore 1571 was Commodore’s successor to the notorious 1541 disk drive. It addressed many of the shortcomings of the 1541, partly because Commodore had more time to get it right this time. It was the same color and style as the C-128. And they worked as well together as they looked together. It was a high-end drive, but I hesitate to call it Commodore’s top-end 5.25-inch drive. I’d give that distinction to the SFD-1001.

Commodore introduced the 1571 in 1985 at a price of $299 US. It was a double-sided, double density 5.25-inch disk drive that was faster than the 1541 when you used it with the 128, and maintained good backward compatibility with the 1541 when needed.

Retrobright with sunlight and no chemicals

Retrobright with sunlight and no chemicals

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.

Amstrad PCs: The PC1512 and PC1640

Amstrad PCs: The PC1512 and PC1640

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.

FPGA vs retro hardware

FPGA vs retro hardware

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.

Monitor for a Commodore VIC-20

Monitor for a Commodore VIC-20

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.

The killer POKE for the Commodore PET

The killer POKE for the Commodore PET

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 59498,62 on the Commodore PET. The infamous killer POKE.

The killer POKE, POKE 59498,62, 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.

IBM PS/Valuepoint

IBM PS/Valuepoint

The IBM PS/Valuepoint was IBM’s attempt to address public objections to the IBM PS/2 series. Introduced in October 1992, they were the most clone-like IBM business desktops since the IBM PC/AT. As the name suggests, they were designed to be price competitive with the higher-end PC clones like a Compaq Deskpro. IBM sold them alongside the PS/1 and PS/2.

Genesis vs SNES: Battle of the 16-bit consoles

Genesis vs SNES: Battle of the 16-bit consoles

The Sega Genesis and Nintendo SNES were natural rivals. They weren’t the only 16-bit game consoles of their era, but they ended up being the two most popular. Sega leapfrogged Nintendo with the Genesis, and the SNES was Nintendo’s answer. Let’s take a look at the Genesis vs SNES.

Overall the SNES was the better console of the two and its popularity reflects that. But the Genesis had its moments, so it retains a following today, even if it has to stand in the shadow of the SNES.

How to hook up a Sega Genesis to a TV

How to hook up a Sega Genesis to a TV

The Sega Genesis connects to a TV in much the same way as other consoles of similar vintage. But there are some dangers unique to the Genesis that give you an opportunity to damage either the console or your TV. We certainly don’t want that. Here’s how to hook up a Sega Genesis to a modern TV without damaging either.

Some Sega Genesis parts are interchangeable with other systems, but not universally. That means it’s very important to verify the AC adapter you plan to use, as well as the AV cable you want to use, to avoid damage to your console, your TV, or both.
