Turing's ACE (1946) computer had BURY and UNBURY
that push and pop a
subroutine's return address from a ptr held in TS31. TS1..TS32 were
"temporary storage" registers each in a recirculating memory (mercury
delay line?) with a cycle time of 32µs. The paper referenced below says
BURY and UNBURY were subroutines but I wonder if they were macros.
Or a gin and tonic delay line, as he (jokingly) suggested as an alternative.
