You really should use terminators.  There are no terminators on any
normal Econet interface, and you *will* get reflections from
unterminated lines.  You may not notice on such a short network, partly
because the protocol is robust, but mostly because the network is short
compared to the pulse lengths.  Nevertheless, I bet your network will
be capable of performing better if you put the correct termination on
each end.

BTW, phone cable *is* twisted, just not nearly as tightly as proper
Econet cable, or Cat 3/4/5/5e.
