If the network works at all. Mine won't work without terminators, period.
I still have a couple of old 10base2/T 6 port hubs that are coupled with
coax--everything else is 10BaseT cat 5.
At one time, I picked up a load of 75 ohm male BNC connectors (the screw-on
type) for next to nothing at a "going out of business" sale. Since I was
using 50 ohm coax, I wasn't able to use them without some pretty severe
modification*, so I stuck a 47 ohm resistor inside of each--they worked
just fine as terminators.
* the severe modification turned out slipping the 50 ohm coax into and
soldering it to a small length of thinwall copper tubing, which was then
the right size for the connector.
