Can I simply change the software cardridge (DR1) for another cardridge (DR5 with DS) and have all the blessings of the DR5 software? The compact KSU 616 is rather old (made in 1988).
Can anybody tell me how to,and what kind of, extra ringer I can connect to a M7100. When I looked at the M7100 R11 connections I saw to my surprise that the middle R11 seems to be for a extra ringer!
