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.
If you misplaced the AC adapter/power supply that came with your Nintendo NES, or it broke, you may need a replacement Nintendo NES AC adapter. Fortunately, you have a number of options.
Most devices are super picky about electricity. Don’t use random AC adapters as a general practice. What I’m about to say applies to the original Nintendo NES console, and the original NES only. I have general advice on replacing AC adapters that applies to other devices.
The 6502-family CPUs in Commodore 8-bit computers famously used 64K of RAM at a time. But in 1985, Commodore introduced a cartridge that added up to 512K of RAM to the 128. Commodore followed up soon after with a 256K cartridge for the 64. How did Commodore RAM expansion units work?
Windows versions from XP onward include a built in firewall. But is Windows Firewall enough security?
Yes. And no. Security answers are almost always complicated. But I’ll explain.
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.
If you’ve built a few PCs, or repaired a few PCs, you have some idea how important the power supply is. If you buy any old tin box that fits, you can probably expect to run into some problems. Here’s some advice on buying power supplies, including reliable power supply brands.
Old PCs, especially PCs from the 1980s to the mid 1990s, have a button with the curious label “Turbo.” On some PCs, a number on the front changes when you push it. Why did old PCs have a turbo button?
Some 90s computer brands are the same as today, but a lot more companies played in the field than now. Profit margins were higher then, so industry consolidation wasn’t the matter of survival that it is now.
Here’s a look back at some of the brands of old, including some famous PC brands, some not-so-famous, and some notorious. The 1990s were certainly a make or break time for many of them.
