Subject: Sun/3-powered 737 flight sim
Something that I thought the folks here would appreciate: a fellow in
Dubai is trying to keep a full-motion Boeing 737-300 sim (from 1991)
running.
The main host machine is a Sun/3E, connected over Ethernet to the operator
workstation which has 2 Sun/3Es each with a cgtwo powering a CRT touch
screen. One of the Sun VME SCSI/Ethernet boards died, and he?s been unable
to find a (working) replacement board.
There?s also a big rack of Concurrent hardware running OS/32, and some
newer PCs for visuals and TCAS.
Plenty of pictures and a video tour of all the hardware at:

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.

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

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

I?ve attached different AUI transceivers to Sun3/E SCSI/Ethernet at least
100 times while running and nothing happened. The Sun 3/E prom has on board
diagnostic which could provide more information on the failure.

I must admit I was a little surprised by the statement that AUI cables
cannot be hot-plugged safely.
I certainly don't remember any such restriction back in the day
(although it's entirely possible that I was never told or have forgotten).
Anyone got a definitive statement from anywhere?
