Dan Bowman kindly pointed me to former Commodore engineer Bil Herd’s discussion of the ill-fated Commodore TED machines on Hackaday. Here in the States, few remember the TED specifically, but some people may remember that oddball Commodore Plus 4 that closeout companies sold for $79 in 1985 and 1986. The Commodore Plus 4 was one of those TED machines. So was the Commodore 16.
What went wrong with those machines? Commodore miscalculated what the market was doing. The TED was a solution to too many problems, and ended up not solving any of them all that well. Read more
Here’s a good question I heard the other day: What’s the difference between a CPU and cores, or the difference between the number of CPUs and the number of cores in a system? The CPU vs core or core vs processor distinction, it turns out, is subtle.
As far as the operating system is concerned, there is no difference, but I’ll explain why. For you, there might be a difference.
I’ve been building PCs for more than 20 years and I tend to keep them a very long time, so it occurred to me that someone might be interested in what I look for in a motherboard to ensure both a long, reliable life and a long useful life.
Technology has changed a lot but what I look for has remained surprisingly consistent over the years.
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.
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.
What is the purpose of a screen saver? Screen savers served both a technical and a marketing purpose. From a technical perspective, the purpose of a screen saver was to keep an image from permanently being engraved in a CRT monitor’s phosphors. But it wasn’t long before screen savers started serving a vanity or entertainment purpose.
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.
DOS veterans may remember messing with expanded and extended memory to get memory above 640K. Here’s what you need to know about expanded vs extended memory, or EMS vs XMS. They are two different approaches to solving the same problem.
One of the most popular add-ons for an Apple II added CP/M compatibility. So I guess it should be no surprise that Commodore tried the same thing. But the Commodore 64 CP/M operating system was a flop. Why?
