Most instructions took from 2 to 5 clock cycles, so I'd venture to say 
that the 6510 ran between .2 and .5 MIPS.  Floating point is implemented 
in software, and since the processor didn't have a hardware multiply 
(and shifts were one bit at a time), it probably took dozens of machine 
cycles for addition/subtraction and hundreds for multiplication and 
division.  I doubt that it ever got much past ten kiloflops, and 
probably averaged lower than that.

John
