I have a '93 4020 fadal with mp32 control and -3 software, and my problem is that there are a few functions that dont seem to be working. When I go into the page editor and hit F for functions it wont do anything and the same for G the auto draw page wont come up. The space bar wont do anything eather, as far as toggling me through the various pages. Do i have a bad memory board? Any help would be greatly appreciated.
