As far as I know, an InfoServer 100 is just a rebadged VAXserver 3100. Whether
it had special boot roms or not I don't know. I've never tried to make one into
an Infoserver so I don't know if it can be done.

The InfoServer 150 is (I believe) a value engineered VAXserver 3100. This means
that all those bits not necessary for an InfoServer were not put on board (like
FPU support I think). So it might be possible to turn a VAXserver 3100 into an
InfoServer 150 but the other way round is impossible. (The IS150 used a CVAX
running at 60ns so it should have been a stripped down uVAX 3100-10e).

Well given that the set of such machines cannot - by definition - grow any
further then you have a finite problem; just keep learning and you'll get
there, plus the later boxes tend to be on the whole smaller and simpler than
their ancestors.
