I wasn't able to find a reference to back it up, but if we're sharing
faintly remembered rumors -- I recall hearing that some grad students
had developed alternate microcode for the 11/730 to re-purpose it as a
LISP machine.
I use the lowercase "M" on purpose, I don't recall that it emulated the
various 36-bit machines known as LISP Machines specifically. Just that
it was a native LISP execution environment of some kind.
That's all I've got. Not even an institution, though I have a very
tenuous notion that UMass Amherst might have been mentioned...
