Yeah, there's good reason more modern AUI-based Ethernet and more modern SCSI systems
use resettable polyfuses...

I have also seen the SCSI terminator power fuse blow when the terminator is hot plugged.

I have a Sun 3/E, including a SCSI/Ethernet board, that ran fine the last
time it was powered on. There is a collector in southern Germany who also
has a 3/E board set. I didn't see any contact information for the simulator
owners.
The originator of the Reddit thread works on this simulator and is the point of contact.
They're really interested in moving off the Sun 3/e rather than continuing to try to
get spare parts etc. I've also suggested they check the capacitors and fuses,
especially on the Ethernet/SCSI cards, since the originator claims multiple failures. The
Ethernet fuse in particular is likely very easy to trip because people these days
aren't used to AUI adapters which generally *can not* be hot-plugged without blowing a
fuse.
