And the final one before the storm: Macintosh IIx. This one is running again, CPU had no clock signal. Chased that back to a bad 74ALS374, and one open trace for the power circuit. RAM issues also ensued, so new 74F258s and now its finally alive!

Here was another pain in the butt one to fix. Macintosh SE/30. Two broken traces, shorted CPU between D12 and d13, two bad LS393, and bad LS166. And bad SWIM ⛈️

Paying attention to Isaias where I am at in the Appalachians. After Helene, I have PTSD.

This was a fun repair, but I got it working! Macintosh Classic II. Needed a DFAC, an EGRET and 2 patch wires. Took me an embarrassingly long time to figure out, swapping between 3 DFACs.

The brave little toaster moment: Muuuuch better 😁. I decided to fix it

Sanded and cleaned up the chassis

Time to take a look at this poor sad Macintosh classic. Probably not repairable but, would make a good test harness for boards

I am making really good progress on repair backlog. Macintosh IIcx logic board fixed!

This is what happens to the original hinge:

techknight @thetechknight.bsky.social · 29/09/2026

This is an extremely complicated part, and I can't get it 100% exact. I can get close, though.

techknight @thetechknight.bsky.social · 29/09/2026

That came out alright, now I have to deal with the part that breaks, that metal hinge support bracket. Brittle magnesium.

Dealing with the next annoyance on the GRiD Gridcase 1530: The hinge bearing. It is plastic, likely nylon and it cracks/crumbles. So, 3D printing to the rescue:

Well... that was fun! XT-IDE BIOS embedded into a GRID Application ROM on the Gridcase 1530

On this topic, it was through the website of this application that I discovered Sonique Player as it was promoted. I would then learn about Winamp around the same time, I was in my early teens back then.

Since I am a data hoarder, I found my old installer for Scour Media Exchange. Now, THIS was a blast from the past. I used this post-napster shutdown, just before I got onto Kazaa. Kinda wished it still worked.

Keyboard cable came in, Close enough and it fits in the trough. thisll do

But to be fair the drive was in sad shape

techknight @thetechknight.bsky.social · 21/09/2026

This my friends is why we don't use doublespace, especially on a drive with bad sectors. Let's play a game of... Well whatever that is 😂

WOW! I need to get a lottery ticket. The machine is actually working after a power supply repair and fresh caps.

All right well it's the end of the road for this guy. Whatever glue they used on these plasma panels goes corrosive and it just kills the panel. Off to the E-Waste bin this thing goes

That escalated quickly. What a PAIN IN THE BEHIND to get apart...

techknight @thetechknight.bsky.social · 19/09/2026

Wow someone really splurged with this one. Has the 386 coprocessor and it has a ram expansion

Time to look at this thing I picked up from VCF Midwest. Compaq portable 386

Well, THAT was a boatload of fun 😅

Much better! I did accidentally get an RJ11 instead of an RJ12, I'll crimp on a new one later

Let's test the keyboard and make sure it works after the cable rigging

techknight @thetechknight.bsky.social · 16/09/2026

Time to clean up and fix this IBM 5155 keyboard, The cable is starting to turn to goo

I brought back way too much "stuff" from VCF. Some of which isn't in this photo as I did not have room and it had to be sent with others. Meanwhile, imma lay down and continue to feel horrible from the con crud/flu
