More Microvax/Ultrix questions...

There are two versions of the Microvax I, the KD32-AA (M7135)
which has the F+G floating point microcode and the KD32-AB (M7135-YA)
which has the F+D floating point microcode.
I understand there are also two versions of Ultrix-32 for the
Microvax, one for each, presumably emulating the missing floating point
instructions, right ?
Since Unix only uses F+D, the KD32-AB is preferable since
presumably the microcode runs faster than the software emulation, right ?
Does MicroVMS (and VMS) use F+G instead ? KD32-AA's are generally what
you get unless you specifically ask.
What is the situation with the Microvax II ? The "Microvax
architecture" only supports F+G (right?)
