Remove rust with vinegar

Dave Farquhar DIY, Toy trains August 30, 2019November 25, 2020

I’ve discussed rust removal before, but some people swear by removing rust with vinegar. I never had much luck with it, but I’ve learned the secret.

The secret to rust removal with vinegar is to rinse the part thoroughly with hot water, immediately. If you don’t rinse it fast enough, or with hot enough water, the part will flash rust. But if you rinse correctly, vinegar is a cheap and effective way to remove rust from toys, old tools, and anything else made of iron or steel. I mostly use it on toy train parts but anyone who deals with anything old needs this trick.

Is USB blocking misguided security?

Blocking USB ports on corporate computers certainly is an inconvenience. But it’s something many companies do in the name of security. The question is, is USB blocking misguided security? Does it solve a problem, or just create others?

There are serious security concerns with USB devices, besides the danger of people copying huge troves of corporate data onto a USB stick and taking that information with them. That’s why many companies, and the government, limit what you can use USB for, or sometimes block it completely.

Matching Commodore breadbin beige

Dave Farquhar Retro Computing August 28, 2019August 3, 2019

I don’t think it’s any great secret that RAL 1019 is the color of the Commodore 64 breadbin and its matching peripherals. But what can you do in parts of the world where you can’t find RAL 1019 in spray cans? Here are some other tips for matching Commodore breadbin beige.

There are several reasons to want to match old computer colors. Maybe you want to paint a damaged case, or maybe you’re building a peripheral for it and want a vintage color for it. Fortunately there are some off-the-shelf matches that are fairly close, including in the Krylon Fusion line, which bond well to plastic.

Does the Nintendo Switch have Ethernet?

Dave Farquhar Hardware August 27, 2019March 13, 2021

Last Christmas we bought our sons a Nintendo Switch. And of course we put it in the room of the house that has the worst wi-fi reception. So I quickly looked for an Ethernet port. When I discovered the Nintendo Switch does not have Ethernet built in, I looked for solutions.

Gotek floppy emulator for retro PCs

Dave Farquhar Retro Computing August 26, 2019October 9, 2019

Gotek floppy emulators are a useful piece of hardware, especially for retro PCs. The problem is they suffer from poor (or entirely missing) instructions. If you mess around with old PCs a lot, a Gotek is a must-have.

A Gotek floppy emulator is a drop-in replacement for 3.5-inch floppy drives that reads images off a USB flash drive. The Gotek can cycle through 1000 disk images on the USB drive by pressing buttons on its front panel. Goteks are really designed and marketed with vintage music equipment in mind, but they benefit old PCs too, for exactly the same reason.

Does a Lionel train have to run in a circular loop?

Electrically speaking, there’s no reason a Lionel train has to run in a circular loop. A circular loop is the simplest way to set one up. But if you want another shape, you can do it.

Why computer cases changed from beige to black

Dave Farquhar Retro Computing August 22, 2019August 3, 2019

For most of the 1980s and 1990s, computer cases were an off-white color people variously called cream, putty, or beige. It changed in the early 2000s, and from then onward, the most common color was black. Here’s why computer cases changed from beige to black.

News vs propaganda

Dave Farquhar Writing August 20, 2019March 28, 2021

A day after watching the Netflix documentary The Great Hack, which is mostly about modern propaganda, I had an exchange on social media that got me thinking about news vs propaganda. What’s the difference? It can be subtle, but here are things I look for, as a former journalist myself.

News follows several rules, but the most important rules are named sources and the quantity. If a story doesn’t have three sources, it’s not news.

Optimizing DOS memory

Dave Farquhar Retro Computing August 19, 2019September 13, 2023

After watching some 486 build videos, it became clear to me that optimizing DOS memory is a lost art. Yes, I made some boot menus and custom DOS boot disks in my day, but for power users familiar with DOS memory management, boot disks were usually a last resort. Memory managers usually free up more than 600K of conventional memory so the overwhelming majority of DOS programs don’t need a special configuration. Here’s how to use them.

The key is using HIMEM.SYS and EMM386.EXE in your config.sys with certain recommended parameters. These programs move device drivers and memory-resident utilities out of conventional memory to make room for memory-hungry DOS programs. Using HIMEM.SYS and EMM386.EXE is a bit of a lost art, so let’s see if we can un-lose it.

Lionel has a storied history, and its ownership has changed several times since 1969. Who owns Lionel Trains now? The answer may surprise you.

Lionel, LLC, manufacturer of Lionel electric trains, is owned by Guggenheim Partners, who also own the Los Angeles Dodgers baseball team. Rock and roller Neil Young remains affiliated with Lionel but his ownership stake is unclear.
