Yes, but atm I don't have a working scanner. Will see what I can do
as time permits.

I doubt that all the parameters directly translated. I'm also am inclined to think they would have had to offload patch data from the X/Xa,tweak them slightly on an external device, then burn them to PROM.
But again, I believe Oberheim's programmers from around that time would probably be able to clarify that.

I believe thats accurate, or more simply its an OB-X/Xa hybrid; it has the same voice architecture (2-osc/2-pole/cross mod) as the first OB-X, but the chip set/sound of the OB-Xa.
The gray units could also be termed an OB-X/Xa hybrid, but with a sound and and ckt design thats just a bit more transitional, compared to the pin-striped units.
It would seem, that gray models were a proving ground for modeling the old SEM OB sound with an IC-based design.
