Subject: Problem with MDM720 on MicroDecision

Your experience with getting MDM711 to work on your machine, but not
MDM720, may be related to the overlay.  For MDM724 the overlay no
longer seems to work beyond the LOGON lable (I got it to work by
deleting everything that did not seem to match after examing
the first bytes and the overlay with DDT).  But I checked the PMMI overlay,
which may not be exactly like your MD version.
I don;t know if the problem goes back to 720.  If you like, I can send
you a copy of the overlay that now works for me, so you can examine it.
Advise if you want that.
