Our sales forces have a customer who has a ancient Enterprise edge 1000. It runs 2.5 s/w. The sales department is recommending dumping the BCM for a new 4.0. They want to know what version or vintage the MBM's are, so they can save the customer money by re-using cards. I am of the belief that you have to actually take the cards out of the BCM to determine this, but I am not sure. Is there another way to accomplish this?
