There are any number of materials you can use to make ties to fill the empty spaces underneath Lionel O27 track. But I think I’ve found the easiest of all. The materials are cheap and readily available and you don’t need anything special in the way of tools. Here’s how to make O27 track ties out of foamcore board.
Smoke detectors save lives, so it’s important to have them. But how many you have and where you put them is also important. If you’re going to go to the effort to install smoke detectors, you might as well install them right. Here’s where to install smoke detectors.
Intel had a hit on its hands with the 8080 CPU and its successor, the 8085. But then Zilog came along and stole its thunder with the compatible but superior Z-80. Intel needed to follow up with something a lot better. The 8086 was what they came up with. The advantages of 8086 over 8085 were numerous, and that’s why everyone knows Intel, and few people outside of retro computing enthusiasts and embedded systems engineers ever heard of Zilog.
Here are the major advantages of 8086 over 8085.
Tenable plugin 63155 and Qualys QID 105484 reference a high-severity vulnerability regarding unquoted search paths. Unfortunately the fix action tends to be a bit vague. If you’re looking for a way to fix the Microsoft Windows unquoted service path enumeration, you’ve come to the right place. Here’s how to fix an unquoted path for Windows services.
It used to be that chapter one of any book about computers explained RAM and ROM. Based on my conversations with computer professionals younger than me, it doesn’t sound like they do that anymore. So here’s RAM and ROM explained, by a guy who learned the difference in the early 1980s.
My favorite engine is the Marx #54 tin diesel lettered for Kansas City Southern. Unfortunately it has poor pulling power. Being a hollow tin body, it just doesn’t have much weight to it, making the marginal Marx motor even more marginal. Here’s what to do when a Marx engine can’t pull.
Commodore used two different chips as the Commodore 64 CPU during its long lifetime. Both Commodore 64 CPUs were proprietary derivatives of the venerable MOS 6502, but unlike the 6502, Commodore and its MOS subsidiary never licensed either of them to other sources.
Like the Atari 2600 CPU, the 6510 and 8500 were 6502s with some changes. Unlike the 6507, the 6510/8500 added capability, rather than removing it.
I saw a photo of an old Coast to Coast hardware store damaged in a tornado recently. That got me wondering what happened to Coast to Coast, and what was the Coast to Coast Hardware Stores history?
Let’s play Jeopardy. The answer: This Pittsburgh Pirates shortstop is the subject of the most valuable baseball card ever made, and one of the rarest. The question, of course, is: Who is Honus Wagner?
But there was more to Wagner than just that baseball card, though that baseball card is a story that captivated generations.
Living mortgage free isn’t a pipe dream, and it doesn’t necessarily mean you have to live in a hovel to achieve it. Ordinary people on ordinary incomes in ordinary homes can generally achieve it in less than seven years. I know, because my wife and I did it. Twice.
My wife and I live in a middle-class suburb in a good school district. By some standards our 1,600-sqft house is small, but we can live there comfortably as a family of four. It took sacrifices to pay off, but I wouldn’t call it extraordinary sacrifice.
