How to disassemble a Tandy 1000EX

How to disassemble a Tandy 1000EX

A Tandy 1000EX is harder to disassemble than a typical 1980s PC clone. And for as popular as this machine is, I couldn’t find any thorough explanation of how to do it. Even the 1980s service manuals for the machine gloss over or omit disassembly. So here’s how to disassemble a Tandy 1000EX, such as to give the case a thorough cleaning.

American Flyer Trainorama backdrop

American Flyer Trainorama backdrop

The question of backdrops, especially for a tinplate layout, is always a difficult question. Lots of commercial backdrops are available today, but modern backdrops often look more appropriate with scale models than with a traditional toy train layout. American Flyer’s Trainorama is a potential solution that works well with prewar and postwar style layouts.

The American Flyer Trainorama was a 3D backdrop, 9 feet long, lithographed on heavy cardstock by Niagra Litho Company. Its catalog number was 790 or 791, and it was only available in 1953. The packaging was a large paper envelope.

MS-DOS 3.31: The DOS you couldn’t have

When it comes to the best operating system to use for a vintage PC, if it has a 286 or better processor, there is little reason to use anything older than MS-DOS 5 or PC-DOS 5. But with an XT, it’s a little different. The best MS-DOS version to use is one you may have never heard of. MS-DOS 3.31 was an upgrade you couldn’t buy.

What is the Up South

What is the Up South

What is the Up South? Where is Up South? The phrase has its origins in the 1920s, 30s, and 40s. During those decades, Black migrants were moving from southern states into midwestern cities, seeking jobs, education, and an exit from the Jim Crow south.

What they found was that the Jim Crow laws in midwestern cities like St. Louis were in effect. The housing and schools were segregated. Maybe there were fewer restrictions than in the deep south, but there were still restrictions on them.

Revive the paint on electric trains

Revive the paint on electric trains

Sometimes a vintage toy electric train has paint that’s too good to restore, but looks too bad to leave as-is. The question, then, is how to revive the paint. While some people use oil, there are commercial products intended for the task that will do a better job.

Paint will absorb oil to some extent, but it can affect the sheen and any oil that doesn’t soak in will attract dust over time, causing other problems. It’s better to use products intended for reviving automotive paint, which will also work on trains and has fewer undesirable side effects.

Update Windows third-party utilities semi-automatically

Update Windows third-party utilities semi-automatically

I used to have and recommend a tool for updating all your third party software on Windows machines. Unfortunately that tool went end of life several years ago. But Microsoft, of all people, has a tool that works suitably. Usage is similar to apt or yum on Linux. It’s called Microsoft App Installer, and at the command line, it takes the form of the command winget.

App Installer is a free tool that updates what Windows Update won’t. That means open source apps, but also some third party apps, and even some difficult-to-update Microsoft apps, like the Visual C++ runtime. It is capable of updating more than 3,000 apps.
