Interesting, I didn't know a /23 could run V7--all
I know for sure is
that it works on /45s and /70s. Do you know any other machines it runs
on? I'd like to try installing on my 11/73 (KDJ11-A) if possible.
I think V7 should run, the only problem is that vanilla V7 doesn't
support the hardware often associated with later PDP-11s. It needs to
be patched if you want to use RL02 drives, for example. You might want
to try V7M (M for "modified" IIRC) which was tweaked by DEC and
includes drivers for a lot of later hardware. It runs great on my
KDJ11-A from two RL02s (one for root and swap, the other for /usr). I
did however need to compile some bits and bobs in order to install it
using VTServer and assemble a new boot block to get the ROM bootstraps
to work.
