I have an infoserver 100. Unfortunately, the infoserver uses a local area
protocol which would require bridging rather than routing to get to you.
I don't have vax ultrix.

A vax ultrix image from any disk smaller than your RA82 should work with
your machine provided there is a generic kernel. I have taken dd image of
(mips) ultrix from a RZ55 and RF71 and placed it on a IBM 0661 400mb disk
drive and had it work. (All through a DSSI/SCSI interface, at that)

Incidentally, what utility did you use for raw writing with VMS?
