I finally gave up and looked at my orange book (decsystem10 assembly
language handbook), 3^rd edition.
You are correct; the KI had DMOVE, DMOVEM, DMOVN to handle double
floating point. The KI does not have \ double integer arithmetic.
As a matter of fact, the DMOVN only works for floating point format;
using it to negate the double integer format does the wrong thing. I
forgot about that once and couldn't understand why my code wasn't working...

I can't remember about the KI - I think it had DMOVE, but not any of
the arithmetic instructions.
