Serial # (was Re: A89: TI89 ROM vs HP49 ROM)




I have used the FlashROM upgrade, twice, and I didn't notice that the serial
number changed.

A suggestion- maybe the serial number is stored in the ROM part of the
calculator, or maybe when the FlashROM upgrade is sent to the calc, it
doesn't write over that area of the FlashROM...

Also notice what the emu says the serial number is when you do a ROM dump...

  just a few suggestions...
