Well, that pretty much changes everything, and you might want to have said
that in the first place.

Basically, VaxELN is an embedded operating system, like the OS you have
running on your washing machine or microwave oven.  It has no user interface.
It has no compilers.

You write the code on a VMS machine with a cross compiler, build a VaxELN
executable with your code linked in, and boot the client machine off it.

You can't modify anything on the VaxELN client.... you would have to have
the host machine running with all the source on it in order to build a new
binary to boot.

VaxELN was a very cool realtime system, but there weren't many people using
it and there are very few people who actually know it.  DEC didn't really
like supporting it 30 years ago, and finding any support for it today is
probably out of the question.
