Doner kebab time.

Mental dental. 📈

Harsh but fair 🤣

🤷‍♂️ and the BBC beat them both. 😅

What are the chances that this has something to do with the video signal being weak? I see these right next to the output of the brightness control.

There’s at least a 7% chance I’m going to be able to put this back together. 😬

What are the chances that this is flux, or something nasty was spilled in there?

Good lord. It’s like Zenith took a bunch of separate products and wired them together to meet Sun’s spec.

The RCA jack on the neck board is where the video signal comes in from the 13W3.

For fun, I’m going to argue with ChatGPT through the process. There will be more arguing if it tells me to lick the anode.

500 screws removed so far and still can’t get to the main PCB.

This should be interesting.

That’s what I was thinking.

They weren’t particularly rude about you.

Hey @jeriellsworth.bsky.social nice work getting the shout out on #353 of the hackaday podcast.

I see.

Wait.

No. No I don't.

How did you get your car through the wardrobe?

Whoops, replied out of line @hrrzi.com

I’d never thought of it like that! So my BBC micro makes a good Emacs keyboard?

Here’s the full keyboard.

Need tech support. I don’t see the redacted text when I copy that out to notepad.

That is amazing. How do I get a copy?

And it runs the hotjava browser.

Result.

@graffias79.bsky.social that was the encouragement I needed, thank you. I pushed on the grippy things and it became obvious (eventually) that I can put the pointy end of a spudger in the square holes of the front bit and push.

Ok. Now I’m stuck and a little scared. I need to work on the voyager’s LCD panel and have connectors to remove.

Do I need to release the snaps at the end, or rotate the far side of the connector out?

Get it wrong, and it’s broken 😬

Help!

Look at that cheeky 32MB memory card!

ChatGPT tells me that those weird crystals on the outside are not uncommon, and likely the way that rosin flux migrated over the past 35 years. I'm going to take it for its word and step away, closing the case as I go. Will pretend I saw nothing.

I noticed this. These (red) potted components are likely pulse transformers made by VAC (a German company that Sun used for high-tolerance magnetic components).

Dirty close ups of the GX (graphics accelerator) and microSPARC

Here's the front. The graphics connector and floppy are disconnected in order to remove the bottom rear cover.
