The 780 had H-float as an option, I think. The 730 might always have had 
it, but otherwise the default answer for me for any of these questions 
is always the 86x0. It had everything in hardware (well, ok, microcode), 
except things like vector instructions, which hadn't been defined when 
the machine was sold. Fairly sure it was the machine with the most of 
all VAX stuff done in hardware.
