I am curious to see what OS's run on an 11/40 without the EIS card other
than RT-11. I am researching this. I have always wanted to learn more
about batch-11.
You mean DOS/BATCH? Yes, that would run on that machine, it's an 11/20 OS. So would
the pre-Batch version of DOS-11 (V4).
Another OS that would run on your machine (as well as an 11/20) would be RSTS-11 (V4, or
I suppose V3 if you can find that), the predecessor of RSTS/E that didn't use the
MMU.
It may be that some flavors of RSX-11/M or /S can be built with no EIS, since it's
supposed to be possible to build a non-MMU version at least of /S. But I don't know
the specifics (no RSX experience).

It looks as though Bill only has RL02 drives on the 11/40 so that would rule out
DOS/BATCH. One of the later 3.x releases of RSX-11M should be OK (4.x seems to have
dropped unmapped support).
