The 11/750 used a special Unibus Exerciser Terminator

diag registers in it.
I think it was an M9313.
Google shows them available from a lot of resellers...
I know the diags used them.... don't know about the power-up self test.
Our 11/750 didn't have one, and I don't think the power-up self-test
requires it.
OTOH, the DWBUA requires a UET module.

... just back from a very succesfull trip to the UK and catching up
on 610 posts since Thursday 4:30 am (when I left home) ...
I checked my working (= booting and running VAX/VMS) VAX-11/750.
Next to the VAX backplane is a UNIBUS backplane and the last slot has
an M9312. Sorry, I cannot look inside to see what is on the M9312.
I suspect *no* ROMs (they wouldnot work), but perhaps interesting
is to see how the jumpers are set.
have fun,
