I used Franz Lisp on our student VAX 11/750 at university, maybe in 1985. I have no idea what kind of license the university had and how much they had paid for it. That wasn't a question you would ask yourself those days, all computers were worth millions.
Around those days the university also bought a Symbolics. But its capacity was well below the VAX so students didn't get to use it without working on any very specific project in just that Lisp group.
