The easiest and least expensive way to connect these systems is to go
out and get one of the new miniature ethernet transceivers, plug it
into the db-15 drop-cable connector, then run coax to the PC.  The new
tranceivers are about the size of a DB connector shell, and run about
$200.  The tranceiver runs off the db-15, so it's a tidy installation.
The coax is ThinNet, cable type RG-58A/U.  Just make sure you're
terminated at both ends!  I saw a review of a couple of brands of
these miniature tranceivers recently, I believe in the September DEC
Professional.

Good luck.
