How much were they new?  ~$400?

I doubt it, since the processor is ~90% of the unit.

My approach would be reverse-engineering, so there would be no dependency 
on the old, obsolete hardware (must be the reason they no longer sell the 
unit: processor no longer available & no easy migration path to new hardware).

Yes, this would be the obvious hard part.  My immediate interest is to 
"decode" the data stream & establish the protocol coming out of the 
controller.  Once that's done, each radio's control format can be 
individually addressed.

Hasn't really happened yet, so I don't expect it to.
