Thank you for the collection of past articles.

Unfortunately, this splicing of Thick (Yellow) and thin (usually
black) Ethernet coax cables is not an option for many sites
with NeXT connection problems.
Our computer center would not allow this, and I would not
either if I were the caretaker of the network. 

The problem is NOT the connection to thick coax, but the
connection to the BLUE transiver cable (containing multiple
twisted-pairs) usually terminated by a 15-pin D connector.
It's really a connection problem to a "DELNI-net".

For this, some sort of active device is needed, and a simple connector
and a splicing kit won't do.
