I would suggest that you have to go back to V4.0 of RT to even still
have the VT11 support in the monitor...

I don't know how many releases they have in their library... but I
also don't know if they would consider selling it...

I believe V5.5 was the release which was current at that time. We were
still working on V5.6, which wasn't released until 1992. It might have
been V5.4, though... Heck, after 15 years of releases, they all sort
of merge in my memory...
