Addendum: the original report from 1947 does not describe this behaviour
yet. The change came in oct. 1948. M-668 mentions it and refers to M-647,
which however is not available online.
So the concept of saving the resturn address in another register is at
least as old as oct. 1948, but again I wouldn't be surprised if some
even slightly earlier computer had it too.
