    This is how I speculate the memory on the TI-89 is divided. First
there is the OS ROM. I'm guessing it to be one megabyte or so. Then
there is the Flash ROM OS part which holds all the catalog functions and
extra system software. This is a megabyte, give or take from the size of
the original rom dump 2048K. Then there is the user archiving Flash ROM
which we know to be 384K. Finally the system RAM 250K. Most TI-89'ers
seem to think the only flash rom is the 384K but forget the OS Flash
ROM.
