For a while, I was the guy who said, "Mobilon bands are fine." The popular opinion in the retro-gaming scene was that they're low quality and wear out too easily, but I knew that wasn't an accurate complaint. The primary problem is, unsurprisingly, the user. Mobilon 90mm elastic bands have been...

Amazing work, thank you @eric

I anticipate that the red spheres located inside the computer serve as positional fixtures for the track ball. If the blue rollers have dried out and shrunk then the distance from the track ball’s external face to the rollers has now increased, reducing contact or eliminating it entirely. just...

The IPA probably dried out the blue rubber, possibly causing it to also shrink a bit. As others have said, I too would guess that they’re not “sticking” to the ball as well anymore :)

Definitely! This could be a great place to add more support for a bolted on reinforcement bracket - or just plain old reinforcement! mod anyone tries it, I recommend a two part epoxy. I’m suspicious that this alone won’t eliminate the risk of cracking (could maybe even make it worse?) but it...

It may be the ram on the GPU - many memory chips manufactured during this time doesn’t seem to age gracefully.

These days I have practically zero interest in the color classics - but jigs like these are so cool! Kudos, it looks great

I am envisioning a perfectly form fitting bracket which is both epoxied and bolted into place — ideally, this will spread the load over the entire upper chassis rather than just the upper segment of the hinge mounth.

The broken hinge cannot be repaired with glue, it will continue to break. I suspect that the existing structure can be reinforced economically (such as metal 3D printing). I’ve been very busy recently but the direction I would explore is a custom 3D printed reinforcement bracket which is...

Thank you, these photos clearly illustrate the hinge assembly. is this a common problem? I’ve not heard of it before.

Is this portion of the chassis removable - a subframe? I haven’t had my portable open in a long time.

Have you ever used alltransistors.com? You may be able to find alternatives which are either still made (unlikely) or has NOS. Perhaps a modern transistor could be used with an adapter board.

Thanks James, my goal is to make premium quality gears available at the lowest price.

Once the “green” 3D printed resin is polymerized through UV curing it’s then reasonable robust. That being said, half an hour may be overkill.

I maintain my ISO with automatic 10 µm and 5 µm filtration, you can learn more about the system from the original author's YouTube video. I highly recommend this for anyone who prints regularly.
