The 750 _could_ use VMB; you just had to load it from TU58. The 750 just
didn't need VMB to boot from disk - it just had a "shortcut" (some might
say
a "hack") for that path.
True. And the hack was pretty much "do it like PDP-11s do". :-)
And I believe the hack worked just as well for booting Unix too; that's
why the 750 was very popular with Unix sites.
Indeed. For all of its primitiveness, this was actually an advantage.
And of course, nobody ever wanted to boot anything but VMS... ;-)
Well, DEC didn't, and they did build the machine after all.
Didn't seem to stop any of the Unix crowd from using it too.

Don't get me wrong. I like bashing the VAX (and DEC), but I actually like the
machine.
