If you ever want to own a microcomputer, remember that recapping a power supply is a LOT more expensive.

Over $300 just for the six bottle caps and another two dozen of the comparatively little axial caps Four Phase use everywhere else.

What kind of a meteor crashed into the handle to bend it that much?

We lost Dennis Ritchie on this day 14 years ago.
Father of the C programming language. Co-developer of Unix.

Never forget the man who helped build the foundation of modern computing, yet whose passing was so brutally overshadowed by a sleazy salesman who disowned his own daughter.

It's amazing how this was 40 years ago and a lot of the computers we now see as vintage and collectible were still barely 25 years old while others were so new they were not even considered out of date yet.

Watching an old video from the former Computer Museum of Boston and they had an Apollo Guidance Computer on display that while they did a beautiful job emulating it on what looks to be a compact mac with a touchscreen overlay, the touchscreen is so badly out of calibration it's completely unusable.

Re-using the liquid cooling system also required me to find out the reason why it was shelved in the first place. It kept losing coolant and now I was able to find out the radiator had multiple pinhole leaks, however because its copper I could fix them with solder. Boom, no more losing coolant!

Some photos over the last year as I began building the system for the LAN Party, testing to make sure it all worked and committing everything to the case as I was repairing cracks and gluing on magnets to support the liquid cooling system.
Thanks again to @thetechknight.bsky.social for the PSU!

For tomorrow's video I'm wrapping up with VCF MidWest and doing a show and tell about a system I brought with me.

I was away for a weekend and I determined now to start filtering job searches into its own folder because this is just nuts.

Yesterday, I was lucky to be able to spend a couple hours at the Connections Museum with Sarah Autumn.

I had a stupid grin on my face the entire time!

Even after a couple hours, we just barely scratched the surface of what's there. It's unbelievably awesome.

Me and Sarah at her favorite spot in the museum. This is used by technicians to diagnose and fix issues within the switches. Sarah explaining how the entirely electro mechanical sender works This video phone works and is from 1970! Needless to say it was a huge flop but you could make video calls.

I had a blast hanging out at the Interim Computer Museum Saturday night. There were a bunch of things I had never seen in my life.

Thanks @celgen.org for being my model!

Punch card sorting machine. Quite mesmerizing! The Thinking Machine is a sight to behold. This PDP has a few faults at the moment, some stuck memory bits I think. Stuff I've never seen in my life.

And somehow I am now on a list with the CBSA. Is it a bad list? No idea. 🤪

The border guard recognized me as “the guy with the clean old station wagon full of old computers” and had apparently processed me in 2024 because again, how to declare value on this stuff.

No issues getting home. 👍

Thank you to Mike Brutman as well for loaning me his Xircom parallel Ethernet adapter and a floppy disk setup with his DOS TCP stack so that I could demo an IRC client running on one of the GRiD’s as well!

Day 1 is well underway and the tables are looking great! Don’t forget that the Interim Computer Festival is also tomorrow if you can’t make time before 6pm today!

Thank you to Josh and the Seattle Retro Computing Society for loaning me some of their own GRiD laptops and a printer to salvage most of my table for the show!

I was told this visit came with a free burger….

It’s 2am and I had to abandon my exhibit at a friend’s place in Vancouver but I finally made it to Seattle. X-x

I’ll see you all at the show tomorrow……er, in a few hours.

I’m not even selling anything! They just want a bonded list of everything I’m bringing down so they can tell it’s coming back and it’s value. How the hell do I value 40 year old laptops where the only listed value is eBay? That’s like grading a car based on the price at Bring a Trailer.
