More or less.
They had better be--one of the big selling points to
us of the 750 was that
you got a considerable hunk of the 780's processing power for a lot less
money.
The 11/750 was physically smaller, used 110VAC (on a 30A receptacle),
clocked in around 60% as fast as the 11/780, but was limited initially
to 2MB (later 8MB, then finally 14MB) and since it had 3 "CMI" slots
could only have up to 3 MASSBUS adapters and up to 2 Unibuses (but not
simultaneously - 1 Unibus came "free", the other took up a CMI slot).
ISTR the price was $300K for the 11/780 and $100K for the 11/750 when
they each came out (basic configuration, not loaded with lots of disk
and max RAM).
