How did the 1802 call and return instructions work?
Clash Royale CLAN TAG #URR8PPP up vote 3 down vote favorite The RCA 1802 processor was used in a number of systems such as the ELF and COMX-35, and also apparently in the US space program (with its hardened variant). From memory, it had a rather unusual set of instructions for doing function calls and returns. Can anyone detail how this actually worked in practice? rca-1802 share | improve this question asked 3 hours ago paxdiablo 286 2 13 add a comment  | up vote 3 down vote favorite The RCA 1802 processor was used in a number of systems such as the ELF and COMX-35, and also apparently in the US space program (with its hardened variant).
