Very few universities offered computer science degrees in the 1970s. Even some of the leading research universities in computer science, including Carnegie-Mellon University eschewed BS degrees in Computer Science at that time. Many academics argued at that time that CS techniques needed to be applied and appreciated in terms of models and problems of specific pre-existing subjects and disciplines that they felt a student should first master at the bachelor's level before concentrating in CS.
This does not mean there were not CS courses in the 1970s, there were, but the degrees awarded were often in other disciplines such as Electrical Engineering, Mathematics, or Physics, Astronomy, Philosophy (Logic) or Cybernetics, Semiotics, etc.
But it is ironic that many companies who want to recruit senior experts in software sometimes screen out candidates from that decade because they specifically require a BSCS for those roles and not equivalent education that may have been only the degrees awarded in that decade.
