....
    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?
   Thanks, Greg Dudek
