system on which to build it). But I don?t believe it would run as-is. There?s also the
issue of terminal interfaces: RSTS/11 only supports DL interfaces (single line
interfaces). And only old small disk drives (RC, RF, RK, RP02/03). And it?s Basic-Plus
only, no other languages.

It looks like this would work, except for the problem of building a RSTS V4 system. I?ve
tried on both SIMH and E11; both fail, though not in the same way. Part of the problem
seems to be that SIMH does things in its DECtape emulation that confuse DOS and/or RSTS
V4.
So I think the best answer is to look elsewhere.
