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.
If your ceiling light fixture doesn’t work, let’s talk about one I worked on last weekend. It wasn’t my first time doing that. I ended up replacing the fixture, but then I fixed the broken fixture afterward.
If you want to know how to save money on appliances, I have some unconventional advice: Buy used. Yes, really. Here’s how to buy used (or refurbished) appliances and save big money without getting ripped off.
I’ve had a number of friends get hit recently with appliance breakdowns they couldn’t afford, and since I’m a landlord, I’ve probably bought a lifetime’s worth of appliances in the last seven years. A dead appliance doesn’t have to turn into a financial catastrophe.
Someone asked me recently about the Lionel CW-80 and how it compares vs older transformers. That’s a fair question, and one that tends to stir up a lot of emotions on train forums. So I’ll try to present the pros and cons in a fair manner.
Changing a worn-out garbage disposal can be a 10-minute job–assuming you anticipate everything, use the same brand as the old one, you know what you’re doing, and the person who installed the old one was at least as competent as you.
It didn’t quite work out for me like that the last time.
I’ve been going through A+ training as I have time. Whether I go through with getting the certification will depend on whether my bosses think having someone with an A+ lurking in the corner is useful–by contract I can’t do much more than swap a keyboard or mouse, but in the meantime I’m picking up some stuff I haven’t had to think about in a very long time.
One thing I picked up is the proper use of an ohmmeter or ohm meter.
Ohm meters measure resistance. Frequently, you’ll have a tool that does several things, so you flip your multimeter over to ohms or resistance to turn it into an ohm meter. Then, if you need to test a cable, put the red lead on one pin, and the black lead on the corresponding pin on the other side. If you get infinite or higher-than-expected resistance, then the cable is bad.
When you’re testing for continuity, you need to do so with the power off. Testing for continuity on a live system will cause the multimeter to malfunction at best, and at worse, blow a fuse. That’s a tricky bit you have to remember if you’re doing component-level testing on a board–something of a lost art these days. You might be testing voltage on a live system, then when you don’t see what you expect, you might want to test resistance. Be sure to remember to shut the system down when you switch from volts to ohms to avoid damaging your multimeter.
