RTI /R-T-I/ /interj./ The mnemonic for the `return from
interrupt' instruction on many computers including the 6502 and
6800. The variant `RETI' is found among former Z80 hackers
(almost nobody programs these things in assembler anymore).
Equivalent to "Now, where was I?" or used to end a
conversational digression. See pop; see also POPJ.
