I probably have a copy around somewhere (I looked and I don't have an online copy, though it may be on the RSTS SIG BBS system in my basement)

There was at least one 3rd-party product that was specifically designed to let RSTS users run their code pretty much unmodified on VMS. From: http://bitsavers.trailing-edge.com/magazines/RSTS_Professional/RSTS_Professional_V04_N03_198206.pdf

"RSTS/E ON VAX
         ROSS/V
(RSTS/E Operating System Simulator for VAX)

ROSS/V is a software package, written in
VAX-11 MACRO. which provides a RSTS/E
monitor environment for programs running in
PDP-11 compatibility mode on DEC's VAX-11.
ROSS/V supports:
•The BASIC -PLUS interactive environment.
• Concurrent use of multiple run-time systems
• Update mode (multi-user read / write access to
shared files )
• CCL ( Concise Command Language) commands .
• An extensive subset of RSTS/E monitor calls.
ROSS/V runs under VMS and interfaces to pro-
grams and run-time systems at the RSTS/E
monitor call level. ROSS/V makes it possible for
DEC PDP-11 RSTS/E users to move many of
their applications directly to the VAX with little
or no modification and to continue program
development on the VAX in the uniquely hospit-
able RSTS/E environment. Most BASIC-PLUS
programs will run under an unmodified
BASIC-PLUS run-time system."
