Anyone old enough to have played with an original Nintendo NES knows the problem: You plug in the cartridge, turn on the system, and get a blank screen and the power light blinks at you. The schoolyard fix is to take out the cartridge, blow into it, then put it back into the system. Then, with a little luck, you can play your game. The trouble is, that’s just a short-term fix. In the long run, it makes the problem worse and eventually the system can’t play games at all. The solution is to clean them. Here’s a process for cleaning NES games.

Coleco Gemini: An Atari 2600 clone from 1983

I spotted it on page 597 of the 1983 Sears Christmas catalog. “Two big names play the same games,” the headline boasted. Next to the venerable Atari 2600, Sears presented the Coleco Gemini video game system, an Atari 2600 clone.

In 1982, Coleco built an add-on to make its Coleco Vision game system Atari 2600-compatible. Atari sued. Coleco poked the bear by making the Gemini, an outright clone. Sears had sold Atari 2600 clones before, but they were actually real Atari 2600s with a different label on them, supplied by Atari itself. The Gemini was more of a true Atari 2600 clone.

What is a game cartridge?

Dave Farquhar Retro Computing June 13, 2017April 30, 20241980s, 1990s, atari, atari 2600, cloak and dagger, colecovision, NES, nintendo, pennies on the dollar, radio shack, Top Secret, VCR, video game

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.

Atari 2600 power supply specs

The Atari 2600 power supply wasn’t as durable as the rest of the Atari 2600, which is nearly bulletproof. By far the most common issue with the Atari 2600 is a dead AC adapter. Fortunately, a suitable Atari 2600 AC adapter isn’t hard to find, even today.

After you replace it with something new, or at least newer, a dead Atari console usually springs right back to life. And if you’re wondering, the same problems apply to Atari 2600 clones like the private-label Sears Video Arcade and the Coleco Gemini and they can also use the same replacement power supplies.

The Atari 2600 CPU: The MOS 6507

The Atari 2600 CPU was a nondescript MOS 6507 chip. Neither Intel nor Motorola had a CPU chip in the early 1970s that could meet Atari’s price point. MOS Technology didn’t have one either, but they asked Atari what they could afford. Then they made one.

The 6507 is so nondescript, some of them don’t even have the number “6507” anywhere on them.

How to connect a Commodore VIC-20 to a TV

Connecting old computers and consoles to not-as-old televisions is frequently a challenge. Sadly, the VIC-20, Commodore’s runaway bestseller from 1982, is no exception to that. Here’s how to connect a Commodore VIC-20 to a TV.

Unfortunately, there are fewer options for connecting a VIC than there are the slightly newer and more common C-64, but I’ll walk you through the options you do have.

The Logitech F310 on Retropie

I went looking for a reliable, modern controller to use on my Retropie setup. I eventually settled on a Logitech F310, betting the Logitech F310 on Retropie would make a nice combination based on my experience with other Logitech peripherals in regards to their quality and value for the money.

The reviews I found suggested the F310 continued in this tradition, and I found enough people who said they got it working with Linux to feel confident I could get it working on the Raspberry Pi. And sure enough, I did.

I paid $18 for mine, and my first impressions of the quality were good. It’s precise, and button pushes register with a slight click. It’s no worse than a Sony, Microsoft or Nintendo controller, and if anything, I think I liked it a little better. A pair of Logitech F310s costs more than the Raspberry Pi board, but playing games is a lot more enjoyable when the controller does what you want it to do all the time, not just most of the time.

The F310 wasn’t a drop-in replacement for the controller I’d been using, though. I had to configure it for Retroarch, the software that provides most of Retropie’s console emulation.

How thousands of Atari cartridges ended up in the desert

The famous story of Atari burying millions of dollars of unsold videogame cartridges, including the infamous E.T. cartridge, is no longer just a legend–it’s been confirmed.

How they got there was mostly a misunderstanding of the nascent business. Read more

The trade off of fidelity and convenience in marketing, and how it doomed my favorite company

Dave Farquhar Retro Computing March 5, 2014July 14, 20171980s, amiga, apple, apple ii, atari, atari 2600, commodore, commodore 64, IBM, kindle, mac os x, macintosh, NES, nintendo, nintendo nes, os x, radio shack, Star Trek, unix

I’m reading a book called Trade-Off, by former USA Today technology columnist Kevin Maney. It’s primarily a marketing book.

Maney argues that all products are a balance of fidelity and convenience, and highly favor one or the other. He additionally argues that failed products fail because they attempted to achieve both, or failed to focus on either one.

An example of a convenient product is an economy car. They’re inexpensive to buy and inexpensive to keep fueled up, but don’t have much glitz and you probably won’t fall in love with it. A high-end sports car or luxury car is a lot less practical, but you’re a lot more likely to fall in love with it, and gain prestige by driving around town in it. Read more

Putting right E.T. for the Atari 2600

Dave Farquhar Retro Gaming April 6, 2013January 19, 2025atari, atari 2600, Star Wars, video game

Hacking vintage video games has been a popular trend this year, so I suppose it was only a matter of time before I saw this: A hobbyist spent a few weeks this year fixing the infamous E.T. cartridge for the Atari 2600, and kept a detailed analysis of the project. I found it interesting.
