The support just plain isn't there.  There isn't anything in src/sys/vax for any 4000 machine, there isn't LANCE ethernet support in src/sys/vaxif, I don't see any mention of any 53C* SCSI controllers anywhere in the source tree, etc.  As Hans said, you're stuck with the older big iron and the older MicroVAXes.  Heck, even adding support for the 4000/200 (still a pure Q-Bus machine) looks like it would be a fair amount of work.

Henry - any idea is you add:   cpu             "VAX4000"

Are you sure that 4.3BSD Quasijarus supports running on a 4000VLC, or
utilizing SCSI devices? Last time I looked it didn't support anything
newer than the pure QBus MicroVAXen and VAXstations, and the only SCSI
devices supported were those on MSCP-to-SCSI controllers.

Indeed, on Quasijarus the GENERIC config file only supports (see
cpu             "VAX8600"
cpu             "VAX8200"
cpu             "VAX780"
cpu             "VAX750"
cpu             "VAX730"
cpu             "VAX630"
cpu             "VAX650"

I think the only Unix to ever support the VLC was NetBSD, or maybe some versions of OpenBSD did too?
