A plea for assistance... I've been working on a program for the Apple II that uses the 80-column card, and am having a bad time trying to get it going on the IIe. The program does cursor addressing by sending characters to the card via the "Pascal entry" at location $c9aa. This works fine on (most cards) on the II+. On the IIe, however, all sorts of extra weird characters are produced and the addressing is not always accurate. I've tried poring over the IIe 80-column card ROM listings to no avail. Can anybody help me? I init the card (in slot 3) by jumping to $c300. *ANY* help would be much appreciated. Please don't hold off responding because you think someone else will -- I don't count on a big response. Is there a standard initialization entry point other than $c300 for use by pascal?
