  The ROM in the TI-89 is not removeable!  It's got a TI-92+ module stuck right
in the board as if it was a normal part of the calc.  The upgradeability is
simply the ability to change what's in the Flash ROM.

  TI will never release the directions for erasing and reprogramming the flash
chips containing the OS.  We'll have to discover that one ourselves.
