In my current job I program extensively on a pdp-11/70 (using Macro-11). I'm curious if these systems have persisted in some areas of industry (e.g. banking)
I don't think there's much demand. I used to work on them but haven't seen or heard about one in decades, except for emulators. But I miss them, and the DecSystem-20. Craziest assembly language ever.
It's many years since I last saw or worked on a PDP-11. The only operational ones I know of are as embedded systems, that includes LSI-11 variants. That is, industrial and niche scientific applications.
I have worked extensively in finance and have never seen nor heard of a PDP-11 being used. A long time ago some DecSystems were in use. But those were all programmed in COBOL.
