Alpha motherboards

I am trying to select a platform for an Alpha Linux system. To that
end I have been trying to compare various Alpha motherboards. If there
are DEC people listening, I got quite a runaround; Digital's DECDirect
doesn't know about them, Digital Semiconductor sends us to
manufacturer reps, reps send us to distributors, distributors don't
know much.... In particular, I couldn't get any pricing info after
full day of trying.

Anyway, here's the info I collected, mostly from the Digital Semiconductor
web site:
http://www.digital.com:80/.i/info/semiconductor/

Please make any corrections. Did I miss any boards that are available
on the open market? I am particularly interested in the on-board SCSI
and ethernet capabilities; is it true that Noname and EB164 lack them,
while Cabriolet has them built in?

SPEC results are estimated, based on similar CPU clock/cache entries in
the published SPEC tables.
