I hate how it plays with our expectations and fears of intelligence in LLMs.

After moving the wrapper in the right place, plain gpib works, but pyvisa still segfaults. Great
While libgpib and by extension the python bindings require you to add an offset of 0x60 to the SAD, pyvisa does not.
libgpib does not check for SAD values outside of the valid range. It proceeds to reference a pointer to nowhere and crashes. There is the bug
Once a general intelligence takes over the planet (and that's only a matter of time imho) it will play with our psyche in very sick and twisted ways since all it is is a reflection of ourself and our combined innermost fears.

It might not even have a real consciousness behind it, just an empty mirror that will stare back at us.
The PSU died for good now. So, it wasn't because I had plugged the fan, there's actually an issue.
A million and two screws
What a pain
Out it is
Output caps aren't that fresh anymore but it's not so bad as to keep it from oscillating
It's not the through hole tantalums either.
5V rail is at 5.1V
-12V at -12.1V
+12V at +12.1V
+24V at 12V

Straight up not having a good time today. Gonna try to funnel my emotions into fixing this mofo.
I checked the Command Module separately with the AT supply again. It's dead, Jim. Maybe independently of the PSU and the PSU was iffy all along. Which I did not notice because the squeaky sounds it makes were muffled by the fan noise. And the faulty 24V line is used only for the fans and I never checked it.

Gonna focus on the PSU first, since I got it apart.
Here's the 24V output.
