I have ran into something that I hope is not an incompatibility problem
with the ROM 03 IIGS machines. I use TML Pascal II to write games for
handicapped children and in order to use the TouchWindow (tm) I have to 
read values from the jostick port. To accomplish this I have been using
a toolbox call to FWEntry to access the routine PREAD (at $FB1E). I works
fine on the ROM 01 machines but does nothing on the ROM 03's. I went into
the monitor (yes, after booting with GS/OS) on both machines and the 
information at 00/FB1E is different. I couldn't find an explanation for 
this in any manual although I don't really have anything on the ROM 03's
that could contain warnings about using these routines.
   Anybody out there with the same problem?? Any help would be greatly 
   appreciated.
