Okay, let's try this again, and see if I can get the headers right.

No.  I never looked for any, though; I just looked at the device, said
to myself "thinnet transceiver", and filed it with "Ethernet stuff I
don't need now but don't want to junk".  It just happened to be out
when I was looking for things that colour, and I recalled DESTAs being
mentioned upthread.

What do you need doco on?  Both of its interfaces (AUI and thinnet) are
pretty well-defined....

If your transceiver is close to your host, you can just use two DB15
connectors with 15-pin ribbon cable between them.  Keep the length
below about two feet and you can get away with a lot - the signals on
that interface are only on the order of 10MHz, which corresponds to 30
metres.  I did this once for a box where the cable had to leave through
a wide but thin gap - appropriate for ribbon cable but not for round
cable.  Worked fine.
