So the entire OS is not stored on a flash rom?  I had assumed that the
entire OS (excluding the routines for receiving the flash rom...) would be
stored on the flash rom.  Would this mean that if they discover a bug in
the "core" OS, it's time to buy a new calculator?

P.S.  If this is already posted somewhere, please post the url.  I have not
been able to find any information about the 89 or 92+.
