Marx made five different type of couplers between 1934 and 1974. If you’ve never seen Marx couplers explained before, here’s a primer on how to identify them and use them together. And I even have a few repair tips if you need them.
Paying off debt involves some nasty math, which is why it’s so controversial. When I was in college, my university used this kind of math to weed students out, so it should come as no surprise that the lending industry booms, and so many hucksters make a fortune hawking questionable ways to get out of debt.
I have a better way, and you won’t pay me anything for the advice. Read on.
CP/M was, as you probably know, the first popular microcomputer operating system. It was good but imperfect, and its cryptic command for copying files, PIP, is often cited as an example.
Copy makes sense. Even the Unix equivalent, cp, makes sense–it’s copy without the vowels. But what does PIP mean? What’s the origin of CP/M’s PIP command?
The Commodore 128 was introduced in 1985 as an upgrade path from the Commodore 64, the most popular model of computer of all time. The 128 was intended to address the biggest shortcomings of the 64 while remaining mostly compatible with its hardware and software. That makes the Commodore 64 vs 128 a natural comparison.
Disassembling a Lionel 1001, 1060, 8902 or 8302 locomotive isn’t too difficult. The biggest problem is knowing where the three screws are that you have to remove.
These particular locomotives weren’t really designed to be repaired, but there’s some basic work you can do on them with household tools. The 8902 and 8302 locomotives can be cheap sources of a motor for other projects.
The Marx 408 street lights are difficult to disassemble. They aren’t difficult because they’re complicated, because they’re not. But it takes a bit of coordination and more than a lot of brawn to get them apart.
But if you need to rewire or repaint one, you don’t have a lot of choice, so here’s how it’s done.
Lionel produced several 35- and 45-watt transformers through the years, including the 1010, 1025, 1015, and 1016. Lionel MPC produced a similar 4045 transformer in the 1970s. They’re small, but cheap when you can find them, and can be useful when you string them together with other transformers. The problem is the markings don’t tell you what you need to know in order to do that.
In the past, I’ve recommended Secunia PSI as a way to keep your systems up to date. I know from my own experience that it helps, but I also know it doesn’t work 100 percent of the time.
When it comes to security, nothing is more critical than making sure your updates are applying correctly. That’s where my employer comes in, with Qualys Browser Check.
When you want to phase transformers, it’s good to know the common (in Lionel terms) or base (in American Flyer terms) post. It’s a shame that Marx didn’t label which of its posts was common. So here’s how to find the common post on a Marx transformer.
It’s a good thing this is fairly easy to figure out, because Marx transformers are dirt cheap. I bought one for exactly one dollar at the last train show I attended, and the vendor wanted to sell me a box full of them for $5.
