How the IBM PC became the de facto standard for desktop computers

Dave Farquhar Retro Computing , , , , , , , , , , , , , , , , , , , ,

I saw a question on a vintage computing forum this week: How did the IBM PC become the de facto standard for PCs, and the only desktop computer architecture from the 1980s to survive until today?

It’s a very good question, and I think there were several reasons for it. I also think without all of the reasons, the IBM PC wouldn’t have necessarily won. In some regards, of course, it was a hollow victory. IBM has been out of the PC business for a decade now. Its partners Intel and Microsoft, however, reaped the benefits time and again.

Using a Lionel (or other brand) O or O27 transformer with HO or N scale trains

Dave Farquhar model railroading , , , , , , , ,

Here’s a good question: Can you use Lionel O or O27 transformers (or, for that matter, American Flyer S transformers) with HO or N scale trains?

The answer is, not directly. It will make a terrible noise if you hook it up. But you can make it work properly if you add a bridge rectifier. Look for one that’s 10 amps or more; don’t expect to have to pay more than a couple of dollars for one. Read more

What to do about a router dropping connections

Dave Farquhar Hardware , , , , , ,

A former classmate and coworker contacted me with a question.

My router is about 5 years old. I have a cable modem and a router. The cable modem is fine. The router keeps connecting and disconnecting from the internet…used to happen occasionally, now happens all the time. I reset it and it works for a while, then disconnects. Is it time for a new router or do you think something else is going on?

I see two options. Read more

A TRS-80 retrospective

Dave Farquhar Retro Computing , ,

This month is the 35th anniversary of the TRS-80, which was the best-selling computer in the world until 1982 when the VIC-20 overtook it. Did you miss it? I almost did.

Veteran technology journalist and editor Harry McCracken has a nice retrospective of this mass-market computer from Radio Shack.

Microsoft just priced its Windows 8-based tablets out of the market.

Extremetech reports that they expect Windows 8-based tablets to sell for $600-$900. I think Microsoft is forgetting its history.

Best Buy needs to clone Micro Center, not Radio Shack

Dave Farquhar Retail , , , , ,

So Best Buy is planning to close 50 big-box stores, downsize others, and try to focus its efforts on selling cell phones, tablets, and e-readers.

Sounds to me like they’re trying to become Radio Shack. Read more

If you’re a tinplate fan like me, it would behoove you to make a trip to Big Lots sometime this week. Big Lots has a selection of building-shaped cookie tins priced at $5 each. The buildings include a town hall, post office, bakery, and general store. Additionally, my old friend Radio Shack is selling a building tin full of AA and AAA batteries for $10 until December 10 (it’ll be $20 after that).

How to wire LEDs and other circuits risk-free

How to wire LEDs and other circuits risk-free

I see a lot of questions about how to wire up circuits, and unfortunately when people ask these questions on train forums, those innocent questions often devolve into heated and unproductive discussions focused on the math and physics involved, or other creative things that overcomplicate the project, and it scares off a number of people, often including the person who asked the question.

Usually what the person asking the question really wants is to not spend a whole Saturday soldering a circuit together, only to find out in the end that it doesn’t work.

So I’ll attack that issue. Here’s how to stage a circuit, find out in a matter of minutes whether it will work, and delay the soldering until you have something promising.

How to solder

Dave Farquhar Hardware, Toy trains , , ,

Soldering is an intimidating skill, but it can be learned. And with some practice, it’s not difficult to learn how to solder.

I’m not a professional. A lot of people are surprised to hear I’ve ever had to solder on anything computer-related, since many people my age haven’t. In spite of the disadvantages, I learned how to do it. If I can solder things that will hold together and conduct electricity, you can too.

Here are some tricks and tips, most of which I’ve learned the hard way. Read more

Smart wiring for the gateman, from the January 2012 Classic Toy Trains

Dave Farquhar Toy trains , , , ,

This week I received an advance copy of the January 2012 Classic Toy Trains. There, on page 42, is my first magazine article in more than a decade: Smart wiring for the gateman.

I’d like to make a couple of clarifications on the article, as space constraints kept me from elaborating quite as much as I did in the original manuscript–a problem I never have online, but almost always seem to have in print. The issue isn’t due on newsstands for another couple of weeks, but I’ll go ahead and post this now.
