In the early days of VMS (say 1.6 through 2.6) there were large parts of

Datatrieve-11 were there but things like PIP helped users COPY and RENNAME
files. Before BACKUP we used an -11 backup utility whose name escapes me
right now (bit rot in the brain). It's been a long while, but I'm sure
there were lots of other PDP-11 images (ISTR FORTRAN was one of them). We
owe a lot to compatibility mode, otherwise VAX/VMS in the early days
wouldn't have been much use at all. (Yes, I appreciate that this ages me
somewhat, but I was a really _young_ VMS system manager :-)

Also, has anybody ever run a VAX11 in PDP mode
for real? Sound
pretty wild to me to spend so much money only to not use the
virtual memory.
The only use of the vax11's pdp11 compatibility mode that I've ever
heard of was to run RSX-11 binaries under VMS.
