In Europe, the computer in which the stack principle was most highly developed was the English Electric KDF9 (first delivered in 1963). This machine had two hardware stacks?onr for return addresses, the other a work stack with arithmetic and logic facilities. Regrettably, the experience gained on this machine was never embodied in a successor. It is worthwhile to look at the origins of its design.
