I too have a similar situation...I have a Mac IIx and an 030 NeXT
cube...I'd like to eventually link them together via Ethernet. Rumor has
it that NeXT will be incorporating support for Ethertalk "Apple's
localtalk over ethernet media" in a future release of the NeXT OS.

Twisted pair sounds nice...AS long as I don't have to buy a "hub". If
twisted pair turns out to be the reasonable answer I will have even more
of an incentive to upgrade to an 040 to get it!

So networking wiring guru's whats the scoop?
