If you're too late (and these days you're almost certain to be too late
with those old boxes,) you either 'make up' a MAC address after you
solder the exterior battery onto the NVRAM module (there is a well
documented procedure on this) or you 'own' a block of MAC addresses like
I do (somebody had officially gotten a big block of MAC addresses for
some embedded project and gave out extra blocks he didn't need. I have
a block of 256 for my personal use).
Or you can find some ancient 3Com NIC, say a 3c503 or the like, 'retire'
it and and steal it's MAC address. Best practice, of course, is to know
the original MAC address to replace.
