The Lionel KW transformer

The Lionel KW transformer was the second largest transformer Lionel made in the postwar era. It delivered 190 watts of power and provided two handles to control two trains. Internally, the design is very similar to the ZW. If the ZW was Lionel’s Cadillac transformer, the KW was the Buick. I always thought Lionels were overrated until I ran a 675 locomotive with a KW.

There was a time when nobody made modern transformers the size of a KW or ZW. Now that they do, the ZW and especially the KW cost a lot less. I remember when a reconditioned KW cost $200. Today you can get one for under $100. An as-is KW with minor issues will cost half that. These days, the KW is a bargain.

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

I had an update on my work laptop 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 Our vulnerability scanner determined one file, MSO.dll, was still out of date.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. Here’s what I do when security updates fail to apply with this error.

Central Hardware, St. Louis history

St. Louis-based Central Hardware was one of the first big-box home improvement chains. It peaked in 1993 at 39 stores in six states in the midwest, employing 3,700 people. It was once the 19th largest hardware retailer in the United States.

Central Hardware’s motto was “everything from scoop to nuts,” a play on the English idiom “soup to nuts,” which means beginning to end. Their inventory was over 40,000 SKUs, comparable to today’s home improvement stores. Its stores regularly exceeded 50,000 square feet. That’s about half the size of a typical home improvement store today, but it was large for the 1970s and 1980s. Traditional hardware stores ranged in size from 2,000 to 10,000 square feet. Its employees wore orange vests so customers knew who to ask for help.

Al Pedrique: RBI Baseball mystery man

RBI Baseball was the first hugely popular baseball game to appear on the Nintendo NES. It featured real baseball teams who’d done well in 1986 and 1987 with actual player names, so kids could replay the 1986 and 1987 postseasons. It also featured two All-Star teams. The National League All Star team included a mystery man: Pedrique, a shortstop. His real life counterpart was Al Pedrique, who briefly played shortstop for the Pittsburgh Pirates.

Al Pedrique was the starting shortstop for the Pittsburgh Pirates in 1987, and the manager of the Arizona Diamondbacks in 2004. Today people probably remember him best for his appearance in RBI Baseball.

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.

Who makes Insinkerator garbage disposals?

Insinkerator is a venerable and popular brand of garbage disposal you can find at at almost any hardware or home improvement store. You can find one at almost any price point you want, whether you want to spend tens of dollars or hundreds. But who makes Insinkerator garbage disposals?

What happened to Tyco RC and trains?

Tyco is a name I certainly remember from my childhood. While I never had either of them, many people my age had Tyco slot cars and/or a Tyco train set growing up. If you’re wondering what happened to Tyco, or what happened to Tyco RC, Tyco trains, or Tyco slot cars, read on.

When I think of Tyco, I think of slot cars and trains. Tyco went out with a bang with one last monster Christmas in 1996, and it had nothing at all to do with trains or slot cars. Rather, it involved a brightly colored furry monster that giggled a lot.

OPS in baseball statistics

Dave Farquhar Baseball September 6, 2017April 15, 2023

Baseball, perhaps more than any other sport, attempts to quantify how good or bad a player is with statistics. Most baseball statistics only measure a small part of a player’s ability. One statistic that gained popularity in recent decades is On-base Plus Slugging, or OPS. Here’s an explanation of OPS in baseball and what it means.

OPS is the sum of a player’s on base percentage plus slugging percentage. Modern analysts argue it’s a better measure of a player’s ability than traditional stats like batting average or runs batted in.

Which wire is hot, black or white? Is the black wire hot?

Dave Farquhar DIY September 5, 2017September 7, 2023

If you don’t do electrical work very often, it can be confusing and can lead to questions. Is the black wire hot? Which wire is hot, black or white?

By convention, the white wire is neutral, the black wire is hot, and a green or bare wire is ground. But the first rule is there are no rules. So if you see lots of different colors in an electrical box, you probably need to call an electrician. But if you see three or four colors, you can probably figure it out.
