The following is available for the best offer to a hobbyist who is
willing to pick it up in Dedham, MA, USA. If the best offer is just
to haul it away that's acceptible - but I do hope to recover some
of what it cost me to have it shipped here a few years ago. It is
currently configured with VMS 7.3 on a handful of RFxx drives and
being used as a hobbyist system. For those unfamiliar with this
model it's enclosed in a cabinet that is roughly 20 inches wide,
12 inches deep, 27 inches tall, and probably weighs 120 lbs. It's
TOY clock battery has recently died necessitating the entry of
the date and time upon each boot until it's replaced. There is also
a TF85 drive of questionable merit and numerous option cards
installed.

Direct offers/queries to mckinneyj AT saic dot com. As noted above
this is for pickup only - because of the size I'm not interested
in shipping. Now here's what the serial console says about the
hardware...
