Hello again from Gregg C Levine
Okay, that's just how I remember the thing. Since I've never had a
chance to work with a VAX, at all, that was my only chance of seeing the
thing. Will that design run NetBSD/vax? Or is it one of those designs
that's stuck being an orphan? The reason being, is that my offer still
stands. I think I might have an idea or three running for the little
fellow.
