There is this.. http://pdp-11.ru/mybk/pdp11/DEMOS.RAR which looks like a bunch of disk images, but they didn't boot for me either in SIMH or a few russian pdp-11 emulators..... Although a little bit of googleing seems to reveal that the soviet pdp-11's had video cards, and were geared more as "PC's" then as mini computers...
