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

manuals.

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.

O.K. Thanks. I knew that at least the BOSS-6 was still
stepper, but had no idea about when the transition to servos was.

And I like the Motorola 68000 series of CPUs, so I think that
would be a nice one to have.

Enjoy,
DoN.
