I have an Ultra 10 running Solaris 8 controlling a mass spectrometer

We can also connect to the Ultra via ssh to download files and do
whatever.

Lately it seems, when people are downloading files the connection to
the mass spec gets stomped
and the program that handles communication between the Ultra and the
mass spec dies or stalls.
I'm told it doesn't happen all the time, but fairly often.

The Ultra 10, the mass spec, a printer and a PC all connect to a hub
(an Inmac Microhub 4
4x10BaseT + AUI hub). Further, there's a connection between the hub

ha, wow. an inmac. How old is this thing?

I'd suggest replacing hubs or checking cables before tossing in new nics,
especially considering that 10Mb networks aren't going to tax an ultra10
in the first place.

We've had the mass spec for about seven years. It was also the mfg's
proto
so the instrument itself is probably around ten or more years old. If
that hub
was with the instrument the whole time I wouldn't be a bit surprised.

And tell me, when was the last time you saw an AUI connector on
anything?

With a few days actually, on an Ascent ISDN terminal adapter, It was still
"new" enough to have a RJ45 jack as well.

In my box of legacy nonsense, I have an IBM branded AUI to 10base-2
transciever.

It's almost as silly as those older NICs that actually had 10base2,
twister pair AND an AUI port.

I think I might have one those too. DE400-???

You know those things really are all over the place if you stop to
look.
I have '90s vintage Personal Iris (in another lab, still working) w/
an
AUI (it goes through an AUI to UTP transceiver). Also that single
board computer in the mass spec I come to find out uses an AUI
(it too gets turned into UTP). Until a few years ago we had a DEC
DELNI that was gathering dust.
