Both the UDA50 and the Deuna boards are big pigs for amps on your
Unibus.  A typical /750 has about 25 amps of +5 power to offer.
Just the Denua and the UDA50 will exceed this.  This doesn't
mean that you have to buy a second UBA.  You can buy an
expansion cabinet with an extra power supply for another 25 amps
(at least).

The TWG TCP/IP has an optional module that allows DECNET and 
TCP/IP to share the same DEUNA.

Lou Salkind at NYU did a Deuna driver for 4.2BSD.
