Somehow, I thought you'd say that ;)

Somehow, I thought you'd say that too ;)

It does. The SIMM's looked pretty standard (apparently, anything other
than the /300* takes some funky 100-pin SIMM's...), so I'm now firmly
believing that these are some variant of /300.

Do you (or anyone else) happen to know of some good documentation sites
for the DEC 3000? NetBSD says that you can run them headless, but then
says "See your owner's manual for information on how to configure your
system to use a serial console."  Bah!
