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

Dave Farquhar Retro Computing June 9, 2017May 7, 20241980s, 1990s, apple, apple ii, asus, compaq, IBM, intel, VGA, x86, XT

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.

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.

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.

Commodore 64 common questions and answers

Dave Farquhar Retro Computing April 14, 2017August 5, 20171541, 1980s, 1990s, Baby Boomers, commodore, commodore 128, commodore 64, estate sales, garage sales, irving gould, Japan, Korea

I hear a lot of questions about the Commodore 64 over and over again. Many of them don’t warrant a single blog post. So here’s a list of Commodore 64 common questions and their answers.

If you want to know when the Commodore 64 came out, how many Commodore 64s sold, who made the Commodore 64, where the Commodore 64 was made, is the Commodore 64 worth anything, are Commodore 64 games worth anything, or if you can still buy a Commodore 64, read on.

How to tell if a baseball card is a reprint

Companies have been reprinting old, rare, and valuable baseball cards for decades. It’s a way for people to have cards of players like Babe Ruth and Ty Cobb who otherwise never could. But that can cause problems too. Here’s how to tell if a baseball card is a reprint.

Commodore 64 vs Amiga

Dave Farquhar Retro Computing March 3, 2017September 6, 20181980s, 1990s, 6502, amiga, amiga os, atari, atari st, commodore, commodore 64, compaq, hp, intel, kmart, motorola, Packard Bell, Personal Computer, unix, XT

Looking at the Commodore 64 vs Amiga seems a little odd, at least to me. After all, the machines were never intended to be rivals. The Amiga was supposed to succeed the 64. Commodore bought Amiga because they couldn’t make a 64 successor on their own, so they intended for the Amiga to replace it. It didn’t fully succeed, and maybe that’s why the comparison is still interesting.

Looking back, the machines may seem similar today. But in 1985 they sure didn’t.

When KB Toys closed

When KB Toys closed is a relative question. While KB Toys went out of business in 2009, the store closest to you may have closed earlier than that. It was a sad end for a staple of my childhood, and possibly yours. KB Toys isn’t the only toy store to go out of business of course, but it was one of the more notable ones.

Meaning of the word commodore

Dave Farquhar Retro Computing January 24, 2017April 9, 20171980s, 1990s, commodore, jack tramiel

Commodore was a high-flying 1980s computer company that imploded in the early 1990s. But the name is a bit curious. What is the meaning of the word commodore?
