I think that PhoneNet required you to insert an RJ-jack that had a
terminating resistor on it (that always seemed to get lost), unlike
Apple's localtalk boxes which self-terminated. [why do I have shades of
Terminator 2 here?] It is a bus type of network, so what's in it?
probably just something that detects if a device is present on each
port & terminated the "ends" of the bus network at a minimum. Of
course, I have none to examine any longer. You might still be able to
find them however.

I am currently using an Imagewriter printer cable to hook up one
device, and that
seems to work ok, and there is no electronics there.. Perhaps the
transformers are
for some safety - decoupling purpose?

wire and connectors? perhaps an odd resistor or two?
I've never had a real Farallon PhoneTalk unit so I don't know, but I
suspect it has some real electronics inside, or a hybrid transformer
like LocalTalk boxes. However, if you're starting from scratch, you
might look at the CapNet subsitute. The first link Google finds for
"capnet localtalk" will find a copy of the document I originally saw
several years ago, at http://www.jagshouse.com/localtalk.html
