Thicknet Transceiver

If what you want is to create the effect of a hub with your multiport MAU you'll
need a section of coax, probably at least 5M long with a 50-ohm termination at
each end and your transceiver in the middle. Sadly, this is not a convenient
way to do things, but if your stations are terminated in AUI connectors, that's
the obvious way to do things. You might find it cheaper and easier to get a hub
and put an AUI<=>TP adapter at each station. If you can't get those, it will
still be possible to use AUI<=>10Base2 connectors and then interconnect your
stations with RG58 coax with 'T's at each station and 50-ohm terminators at each
end. That thicknet is pretty painful to accomodate, particularly with all the
AUI cables.

I've found these adapters at junk sales from time to time, and it's only cheaper
to use the multiport MAU that you have if you already have the AUI cables.
