We have looked into emulation, acquiring our own VAX 8650 system, and using a cross compiler, but so far we have not had any luck with any of these approaches. I am writing this to see if any of you fine folks have any suggestions as to how we might proceed.

Some of the initial responses (including my own) were based on the
assumption you were running VMS on the VAX 8650 system instead of,
as it turns out, VAXELN and hence the original assumption was that
you wanted to setup VMS on a development box as a clone of your
production box.

Given that you are instead actually running VAXELN on the target box,
the question should be what VAX hardware was used to develop your
VAXELN application originally as that's the hardware you need to
emulate.

Hopefully, you still have the licences and media from the original
VAX development system around and hopefully the licences allow you
to recreate the original development system in an emulator.

The ideal solution would be if someone made a standalone backup of
the original development system on a media format which is restorable,
either directly or indirectly, into your emulator.

Simon.
