The 9511 was the floating point unit, and the 9512 was for 64-bit integer
arithmetic, I believe. I've actually got one of each of these from back in
the old days. They were sort of a calculator for your computer, in that
they could be operated faster than the cpu could perform the function . . .
MUCH faster.
