Greg, I am in Melbourne and very interested in the 11/73.  You might have noticed in my earlier posts I'm a 2.11BSD experimenter, it would be really, really great to have an 11 running 2.11BSD on my home network for experiments.  Do you have a DEQNA?  It would be well looked after, though space is a problem sometimes (as it is for everyone) and I may have to put it in storage from time to time in my father's warehouse, I keep a lot of my computer parts there.  Like you, I am keen to see these important artifacts preserved.  If for some reason I couldn't keep it, I would probably donate to the Australian Computer History Museum, the only problem with that is they're in Sydney.  I would be really keen to see some of these computers staying in Melbourne where enthusiasts could access them...
cheers, Nick
PS. My wife will be furious ;)

I wasn't aware of a MicroPDP-11, but I have an LSI-11/73, photos at
Clearly it's a little larger than a MicroVAX.

If anybody's interested, this machine is up for grabs.  I don't want
any money for it, just the knowledge that it will be looked after.  It
comes with a lot of tapes and (RL-02) disks, and also lots of
documentation.  If anybody here in Australia wants it, you're welcome
to come and pick it up.

This one does.  I gather the architecture  is identical to the
PDP-11/73.  One of the tapes includes the 7th Edition.
