Neither I, but i'm really only knowledgeable of IPC/SS10/SS5 era , not
so much 1+ for example.

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?

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.

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.

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 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.

Sun/3-powered 737 flight sim

2020-08-17 Thread Brendan Shanks via cctalk
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:
