Speaking of Asante Friendlynet stuff, I've got a
few inline 10Base-2
adapters that I have no information on. Each has 2 BNC and 1 RJ45
connectors on them. I'm guessing these use some sort of special cable on
the RJ45 port to connect to the computer? I found a cable loose in another
box that has an AAUI connector on one end, and an RJ45 plug on the other.
Would this be the type of cable used by them?
That sounds like the Farallon transceivers. They had an AAUI to RJ45
cable, and then a box that plugged into that RJ45 end. The box would then
go to whatever port type you were using.
So yes... that cable should go to the box's RJ45 port (which should be
labled as Computer, with the 10b-2 side labeled as Network... at least
the 10b-T ones I have are labeled that way)
I have always wanted to just plug that AAUI to RJ45 cable into a hub and
see if it works without the box... but I have never been willing to risk
frying something.

You won't fry anything, but it doesn't work.
I found one of these AAUI-RJ45 cables a while ago, and thought, "that
can't work, can it?"
I couldn't figure out what else it might've been for, so I grabbed it, and
sure enough, it doesn't work. Now at least I know what it was for.
Folks were forgetting a few threads ago that the ethernet spec defines
media interfaces which are electrically isolated to 400 volts. Want to
know more? Search Google Groups for "etherkiller" in alt.sysadmin.recovery.

was really good about labeling their transceivers, while most companies
didn't bother.

That won't work. AUI ports are for connecting to a transceiver, and
without one, there isn't any way to talk 10Base-T. If you look at older
combo ethernet cards, you can often pick out the 10Base-2 and 10Base-T
ethernet transceiver chips and the 5VDC to 9VDC voltage converter module.
External transceivers usually contain nothing more than a transceiver
chip, voltage regulator or converter, a few support components, and the
connectors.
Speaking of transceiver chips, anyone have a loose 8392 chip laying around
that they don't need? I don't need badly enough to steal one from a junk
board, but I'd like to replace a dead one on an old NIC I have around here
someplace. I found some 8392 chips locally, but the guy seems to think he
can get $16-18ea for them (same place that wanted a fortune for 1771
chips, see the thread from last Nov). Failing that, anyone know of a
dealer selling those chips at *sane* prices? Best I could tell,
$0.20-$0.35 was the going rate for single chips when they were still
available in production volumes.
