I know this is a needle-in-a-haystack question, with very little
information to go on.  But the MMD is such an exceptional resource that
I'm moved to submit it.

Terry Bennett (terryscg@hvcs.net) is trying to find out more about
a music box or music machine that he saw in a San Diego shop in 1976 or
1977.  He says it had "exceptional orchestral sounds" and was rather
expensive.  He believes he was told that some engineering students from
the University of Chicago had developed them and put them into limited
production.

The catch here is that I don't believe the University of Chicago ever
had an applied engineering department.  It certainly didn't when I was
there in the late 1950's.  I wonder if he could be thinking of Dwight
Porter's disc boxes?  Were they around in the mid-1970's?
