One of my 3032s has a 80 column addon card, which in fact is a rebuilt 8032 video circuit. It works fine with the 9'' crt. I never tried a 8032 mainboard though. Maybe the signals have to be inverted. For the sync signals, there are inverters installed on the 8032 mainboard that can be activated/deactived with jumpers.
