Suffice to say, I think my hinge repairs on my 180c are holding up OK

The weather's nice, so I brought the Basement Retrocomputing Dungeon outside

New hardware project: an adapter to connect an HP logic analyzer directly to the PDS slot of an SE/30. Mostly just built it out of curiosity, but it could be a powerful tool for troubleshooting faulty machines or developing new hardware. Expect a writeup soon

It’s not a DIY electronics project without a few bodge wires

Let’s see how many 68k machines I can precariously stack on this flimsy folding table…

Design for the next (and hopefully final) SEthernet/30 prototype coming together nicely.

Powered on my long-suffering SE/30 this afternoon and something went "bang." Time for some power supply surgery, I suppose.

current status: in a battle of wits with GCC's optimizer. My driver works beautifully when compiled with -O2, but fails miserably with -O3. Either GCC is being too clever, or (more likely) I'm being very stupid.

ahahahahahahahahahaha, turns out the deadlock bug I've been chasing in my Ethernet driver might not be a 'me problem' after all. My IIfx with an Asante NuBus ethernet card locks up under the exact same circumstances

More success with my SE/30 ethernet card driver! Managed to track down a very subtle bug that was causing lockups when mounting large Disk Copy images from a network share.

It's working pretty nicely now! Just got to get around to finishing that next hardware revision...

Going more than a bit mad trying to get my ethernet driver to work. I'm clearly just getting some register-saving thing wrong or off-by-one-ing a memory copy but I've gone over it so many times and I just can't see where I could be going wrong.

My notes on monitor sense codes look like something you'd find in some cryptic video game puzzle

You know that you're getting into some serious debugging when you have to bust the oscilloscope out.
