I have this Microsoft Premium Softcard.
The 80 Col. mode seems to be ok with most of the programs.
But if I start the CPM Disk for this card, the coursor just switches into 80 Col. - nothing more possible.
I tried to start A2eDiagnostics - but nearly the same - the program starts - switches into 80 col. and then stops.
Which kind of RAM is on this card - not the same like in an Apple II+?
