I would rather say that the alternative to an HP65/67 would have been a programmable desktop calculator. They became available a decade before the HP65, either from HP themselves or (somewhat cheaper) from companies like Compucorp, Olivetti, Wang, ... They were still rather expensive and maybe only one per department would be acquired, but cheap compared to a mainframe. In the mid 1970ies even our school had a Compucorp calculator on a trolley that only teachers were allowed to touch, operate and demonstrate.

The big change that the HP65/67 and Ti SR52 brought about what that from then on every scientist or engineer or statistician or mathematician could have his own scientific progammable calculator for himself.
