This is a Team Super 1984 with mostly the same features:
I think later than 1990. I had an '87 Quantum, it had the special mounts on the top of the downtube for shifters to mount with internal cable routing. That had changed by the time I had a '95, they had moved to standard side of the downtube mounts for shifters or cable stops as used by STI, cable routing was also external .
