And to this I would add:

IIRC, EB64/EB64+ systems had firmware in a hard ROM.  To confuse the
issue, lots of times follow-on boards like the AlphaPC64 are called an
EB64, just like NetBSD used to call every AlphaPC164 an EB164. Either
way, I don't believe there is a gatekeeper SRM for this, but the
resellers seem to usually have a way to get it for you.  "Make it a
condition of your order."

I also think these boards use a somewhat unusual power supply that has
both 5v and 3.3v outputs but uses AT connectors. You should (1) buy it
assembled, or (2) with a PS, or (3) know where to get such a PS, or
(4) use an ATX power supply if you know how to crimp on new connectors.

I managed to snag one of these supplies for $6 on the necx "outlet
center" page two weeks ago, but they seem to be gone now. (I should
have ordered more!)
