I used a Varian 620 about 20 years ago. I have manuals on the hardware,
microprogramming, assembler, and on VORTEX, the Varian OS.

I have a disk pack that may still be readable (same packaging as an
RL01/RL02 pack), tape backups, and some source and binaries. The programs
are mostly system utilities that I wrote while in school.

I don't have VORTEX, however. I DO have some VORTEX source code listings,
but that won't help at present...

You're welcome to whatever you need. I'll look up the overflow flag
