How to use a Commodore 64

How to use a Commodore 64

The Commodore 64 is rather unlike modern computers. It has a CPU and memory like a modern computer does, but the operating system and overall user experience is alien to someone used to computers that run Windows or Mac OS. So to modern eyes, it’s not completely obvious how to use a Commodore 64.

Commodore had a dominance of the market in the 1980s that would have made Apple jealous at any point in its history, but ultimately Commodore lost, so the Commodore 64’s bloodline is extinct.

Commodore 64 operating system

Commodore 64 operating system

The Commodore 64 didn’t have an operating system in the traditional sense that we now think of one. It most certainly did have a method of interacting with the user and handling I/O, including disk files. But the way it all worked seems strange today. Here’s what made the native Commodore 64 operating system different, and the alternatives that surfaced during the 64’s long life.

The Commodore 64 is by far the most famous and successful computer Commodore ever made. But there were numerous Commodore computer models over the years. Some were also successful. Some were complete flops. Overall Commodore had a good 18-year run, but it could have been so much longer and better.

Let’s take a walk through the Commodore computer models from the beginning in 1976 to the bitter end in 1994.

What is retro gaming?

What is retro gaming?

What is retro gaming? The specifics depend on your age, but it generally means playing vintage (retro) video or computer games today. The part people argue about is what constitutes retro.

There isn’t a lot of agreement or consensus about that, and I have some ideas why.

Computers in 1985: It was a very good year

Computers in 1985: It was a very good year

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.

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.

The Atari 2600 CPU: The MOS 6507

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 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.
