I think this is just great, the fact that you're sincere about the unknown factors here is what makes this really interesting and entertaining to watch. Looking forward to the next chapter! 😃👍🏼

"the computer makes a soft ticking sound, as though there's a time bomb inside."
They sure don't make user manuals like they used to.

The reason why there’s less of the proprietary keyboards is Apple used a cable that has the data and power lines swapped on one end, and many people used standard RJ phone cables, which sent power through the data lines and fried the microcontroller

15:35 Just imagine seeing "there's a time bomb inside" in a modern manual.

"I hope to get the SE running on an SSD eventually."

Druaga where you at.

1987: Macintosh SE

Party at David's house:

"Don't use those plates; they're for mixing epoxy!"

Story time: Back in 1997 I had just started adulting and was working at a newspaper. They had these available in the newsroom and they were old enough that some of the menus had burned into the screen (screen savers weren't just for when you got bored back then).
So some of them weren't working and our cheap manager was trying to repair them instead of upgrading. He called the only person he could find that had parts.
After they had been talking for a while, the supplier asked him where the intended to display them. Cheapo manager was like, "display them, what do you mean?". The supplier said, "Well are you going to have them where someone can touch them, are they going to be on, are they going to be behind glass or anything like that?".
When the manager said he wanted to repair computers so people could work on them supplier guy freaked out. "YOU HAVE PEOPLE USING THESE? LIKE RIGHT NOW? I THOUGHT THESE WERE FOR A MUSEUM!?!?!"
Bottom line, we never got the parts and got some newer (used) computers.

Proprietary, expensive, hard-to-replace hardware?  Oh that definitely doesn't sound like Apple  at all - lol

I was working at a local computer recycler a few years ago, when I was given an old Macintosh Plus to trouble shoot. I turned it on to discover that the the CRT did not seem work, so I followed my instinct. I gave the computer a good whack, then it lit up bright and sharp as ever. Immediately following this, I uttered a loud "Ayyyyyyyy."

Safety Warning: The fire extinguisher you're using doesn't work, it's on the Consumer Reports "Don't Buy: Performance Problem" list because when you attempt to use it, the trigger mechanism will often break and it won't discharge (Amazon reviewers complain of the same thing). I'd recommend a 2.5lb standard ABC fire extinguisher for small uses like that. More generally, you want the largest extinguisher that all potential users can comfortably lift and use, which is often 10lbs (weight is for the extinguishing chemical and doesn't include the tank and such). Sorry about the unrelated nitpick on your great video :)

When looking for main filter capacitors for my 1979 receiver, I found new capacitors about 1/3rd the size, and even higher capacities.

Hot glue is considered a, “stability kit.” They charge like $20 for glue and two zip ties at the mod lab I work at.

When CRT's aren't used for decades they have a very dark picture. This goes away after some used. I don't know what the exact cause is be it a reaction in the phosphors in the tube or corrosion.  On a podcast I heard about a really old and rare computer that had a lot of work put into it but once it was working the screen was so dark that it was unusable. After about a month of being left on the screen had gradually recovered back to normal brightness.

lol, I found a macintosh plus with keyboard, mouse, and cables in a dumpster.

"still iconic today as evidenced by its appearance in this show from 18 years ago"

It's... It's...

For it's time, the macintosh plus was pretty ａｅｓｔｈｅｔｉｃally in my opinion

I have always covered the hole on the disk to convert it from HD to DD. Some may be against this, But i have not had any problems doing this.
