the DD-1 (I used to have one) uses the 8-pin DIN plug. Some ads/posts on the internets leaves me to believe that the DMD-2 can drive the MT-1.
but if you're in doubt, use a multimeter to check the wiring on your new motors. these are ordinary unipolar steppers so easy to figure out (use the pinouts from the link above).

I know there's a difference in the go-to motors as they're closed-loop with built-in encoders (I used to have one) and I think they're servos rather than steppers anyway.

Definitely the GoTo (except the original SkySensor) uses different motors. The 48 ppr, 120:1 motors are too slow for GoTo, running full-bore they can only do 40X sidereal or so.
