The 11/782 is two 11/780 systems connected together via a (MA780?) 4Mb
shared memory cabinet. This system supported ASMP and the story I heard of
at the time (from a reliable friend within Digital) was that the person
responsible for the changes required to support ASMP did it over a weekend....
There was a 11/782 at Melbourne University (not far from here) and due to
the inherent problems of ASMP (all I/O and kernel processing had to occur
on the master system) found that they got much better performance splitting
it into two 11/780s...
There were also rumors of our Defence Department running an 11/787 (two
11/785s in an ASMP system).
