XOR?
When talking about the PDP-11 EIS, it's a little complicated. You have the KE-11, which was the separate EIS option for the PDP-11/40, and you have all the other PDP-11s with EIS by default. The complication is that the instructions provided differ in that XOR was not included in the KE-11, but on all other models. So the question is, should XOR be mentioned on this page or not? --Bqt (talk) 18:36, 27 October 2022 (CEST)
- Actually, XOR was included in the base KD11-A of the -11/40, which is why it's not in the KE11-A. And there's also SOB, SXT, MARK, and RTT in the base KD11-A, which are not in the -11/20, -11/05 and -11/04, but are in all the later machines, including the LSI-11. Those are covered here. So I'm not sure there is an error? Jnc (talk) 22:43, 27 October 2022 (CEST)
