The chip is for the manufacture assigned MAC address. All DEC 
controllers for anything that could talk DECnet was always able to 
change the actually used MAC address in software, since that is a 
requirement of DECnet.

DEQNA and DELQA works the same. In fact, in most ways, they are 
compatible enough that the same software can be used with either 
hardware without changes.
