I think that the BOSS-8 *may* still be using stepper motors as

(And yes, that was properly spelled with all upper case -- an acronym

When they moved to servos they must have had to change the CPU,
and probably had the ability (and experience by then) to add lots of
extra features.


No, the BOSS 8 is also a servo machine, and uses a Motorola 68000 CPU.
Really, a totally different system, with a CRT instead of a row of LED
displays. I think that is true of the BOSS 7 as well.
