Unibus VAXen basically means VAX-11 machines.
They booted either from VMB on console media, or
(for the 11/750) from a boot block.
TO be fair, the limitation on booting was mostly just that nobody bothered
to implement support for any other device in VMB. It wasn't any kind of
hardware limitation.
Later versions of VMB (e.g. in a MicroVAX) could boot directly from
various tape devices.
Really? Not from tape? Interesting design choice...
Old VAXes booted standalone BACKUP from the console media (TU58 or RX01).
SA BACKUP then could talk to tape drives just fine. It's all you need to
install VMS, so that was all they did.
