I kind of wondered if it didn't have something to do with those adapters.
I guess I'll have to try to locate a short coax cable for this setup.

I bought these cards because they were available for $10 each at a local
computer show.  Unfortunately, they only have 10base2 (the BNC connectors),
so a crossover connector is out of the question, unless there's some way
to convert them.

My main concern at the moment isn't to set up a network, but to provide
a faster way to transfer files between my notebook computers than either
floppies or my parallel port zip drive, and also to learn a bit about
networking in the process.

Anyway thanks for the help.  At least now I know what I need to get to
make this setup work.
