The CDC machines 7600, Cyber 70 series, etc used that method to store
the return address.

Surprising that those machines should take a step backwards,
in view of around a decade of Algol (with recursion).

It meant that each subroutine/function needed to implement its own
stack should it be called recursively.

Alan Turing designed the push-down pop-up stack
for subroutines back in 1945, for his computer (later
christened Automatic Computing Engine).
That feature did not see hardware at that time.
However, the Pilot ACE (1951) included a push-down stack
(or, if you like) a queue.  That push-down stack was
continued into the DEUCE line (1955).

The stack as a means of calling and returning from subroutines/
functions was implemented in the KDF9 (1961, delivered 1963).

The S/360 and subsequent issue stored the return address in a register.
That made it somewhat easier to have a universal stack manipulated
by software.
