  I think "common" is a matter of geography. Now, flip chips are much
easier to ship than big BA11 chassis, but...I've been looking for a
simple, run-of-the-mill pdp11/34a system around here (Maryland, DC
area) for the better part of two years...no dice...and many people
say the 11/34 is one of the most common DEC machines around.

  I think some sort of central "clearing house" might help...we all
have projects involving machines that need one component or another.
Many of us will ask our local friends, then post to lists like this
one, etc., and often the results are good...but sometimes not.

  I'm just thinking aloud here; this is a half-baked idea...maybe some
sort of web server with long-term lists of stuff we all have available
on the trading block, and maybe wish lists as well. Something to
facilitate better communications amongst folks like us that don't
necessarily know each other. Any thoughts?
