I've
acquired a few Asante FriendlyNet Thin Adaptors. These are little

electronics there for it to be
a 10baseT - 10based2 converter.
My thought too. There would need to be a 10baseT transciever IC for a
start.
Now why anyone would use a RJ45 in place of the
standard DA15 I don't
know, but certain companies are well-known for deliberately changing
standards for no good reason.
I hope you're not suggesting that because I mentioned it came from an Apple
environment ;-)
It sounds simple enough to trace out the schematic in
about 10 minutes. I
wonder how it compares to the standard 8392 application?
I traced enough of it to convince myself that it's pretty well identical
to several other 10base2 transceivers I've repaired or otherwise taken
apart over the years, except for the built-in 50 ohm terminator and the
substitution of an RJ45 for a D-15.

I'm trying to think of any interface on the Mac
that is in any sense
'standard'. And no, I can't think of one...
Their serial and printer ports are rs232 ports. their USB is entirely normal.
They set the db25 scsi 1 standard. :)

The Mac's serial ports (the printer port is serial, too) are RS422.
And the D25 SCSI is no standard.

At least on the early U.S. models, the power cord seems to use the
"normal" connector and wiring.

I'll agree that Apple sometimes carried their "Think Different" slogan
a bit too far, but in this case they had a reason. What they expected
users to connect to the original serial card (not the Super Serial Card)
was a Teletype, which of course would be wired as DTE.

What use would a teletype be connected to a Mac, which runs an entirely
graphical operating system? Debugging?

Eric is referring to a card that goes in the ][-series
machines.
Oops. I'm reading a lot of vintage Mac lists, so I'm having a hard time
keeping the lists apart. ^_^::
