My Guess is it is a UCSD. It is old enough to have been a bike boom bike so it may well have been their "house brand" bike and they loaded up with what the buyer wanted.
They are still around but my guess is you will not find out much calling them due to the age of the bike.

If you search UCSD Bike you will find a lot of links for racing and Co Op types of events.
