It's possible that the first Massbus support in RSTS didn't allow mixing RP and RM, but it certainly appeared soon after, I'm pretty sure by V7.0 at the latest.  So as of that point, RSTS supported two Massbus adapters for disks, and each of these could have any Massbus disk on it.  Even an RP07, on an 11/70 at least, though officially that was not supported (DEC didn't sell that device on lowly PDP-11s).
