Motorola Software Version questions

What Version of the Motorola software does a guy need to use to program an MCS 2000? is it the same version as a CDM 1250 radio. And also you have to use a rib box to program the MCS 2000 correct

There is a MCS2000 RSS (not the Professional series CPS). Had to be a 32 bit OS, and yes you need a RIB.
