Emu XL-7 & MP-7 User's Group

Very cool post. I always wondered about this kind of stuff. I've read that E-MU upgraded their converters and CPUs during the course of production but was never quite sure if it was marketing hype or what. Do your motherboards have what looks to be another ram/rom slot on the opposite end from the 4 sound roms? I noticed it on my Vintage Pro, but not my XL-7. I wonder what it is for?
