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 update is already installed on this system

The update is already installed on this system

I had an update on my system in a partially installed state. Our vulnerability scanner determined one file, MSO.dll, was still out of date. It recommended a patch to apply. Running it gave me an error message. Here’s what to do when Windows says the update is already installed on this system and refuses to let you do anything but click OK.

Because hey, from a security analyst’s point of view, this is anything but OK. I get questions about patches in a partially deployed state all the time, so I figured I’d write about it.

Thank you, Jerry Pournelle

Longtime computer columnist and science fiction author Jerry Pournelle died on Sept 8, 2017. I count Dr. Pournelle as one of my influences.

I was never a big sci-fi fan, so I’ve never read any of his novels. I really enjoyed his computer journalism, however. He was a tech curmudgeon, and he was blunt, but frequently that was what we needed, especially in those early years when computers didn’t work as well as they do today.

Disadvantages of the 8086 microprocessor

Disadvantages of the 8086 microprocessor

An 8086-series microprocessor, the 8088, powered the original IBM PC. Its direct descendants power PCs to this day. Not only that, they power modern Macs too. This was always controversial, especially running Mac OS on Intel chips. Why? What are the disadvantages of the 8086 microprocessor?

Who still uses Wordperfect?

Who still uses Wordperfect?

I had an odd question come up the other day: Who still uses Wordperfect? It’s a fair question. Wordperfect, as you may know, is still very much in production. Corel releases new versions every year or two. It’s the #2 word processor in the market, still. Someone is still using it, then.

Why did IBM fail at PCs?

Why did IBM fail at PCs?

If you ask why did IBM fail, I assume you mean why did IBM ultimately fail in the personal computer market. IBM is still in business, after all. But its exit from the PC market after 24 years, including a period of dominance in the 1980s, does seem curious. And it raises another question: What does IBM do now?

I experienced IBM’s fall in this market firsthand. I sold computers at retail in 1994 and 1995. IBM’s computers at that time were no worse than anyone else’s, but I had an extremely difficult time selling them. Many consumers didn’t trust IBM and didn’t want to get somehow locked in. There was nothing wrong with those machines, but it sure was a lot easier to just sell them a Compaq.
