Unix ports on LSI11/73 ??

[Steven M. Haflich]

For several more years our site will be running large, CPU-bound PDP11
software which software cannot easily be ported to 68000s or Vaxen for
reasons not pertinent here.  As the application does little IO and is
limited entirely by floating-point speed of the PDP11, we are thinking
of obtaining several LSI-11/73's (the "11/70" on a card, using the J11
chip) and configuring them as stripped-down Unixes connected over
Ethernet.  As these machines would not be supporting real users, but
would only have infrequent large jobs shipped to them, we would prefer
even to avoid the cost of local disks on each machine.

My question:  Has anyone actually ported any Unix (e.g. V7) to the
LSI11/73?  Any particular horrors about it?  [I already *know* the
horrors of porting to and running diskless systems -- so don't flame
about it! :-) I would probably put some minimal disk on the firsts such
system anyway.]

Thanks for any responses.
