Not really a simh question, but this might be an appropriate bunch of people. What actually used MARK on PDP-11?
I think I recall that some Fortran system (F4P?) used it, but that's a vague feeling at most. Certainly as a Macro-11 kernel-mode weenie, I never felt the need. _______________________________________________ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
