I was looking through the TI-89 ROM (2.05) today and found what appears to
be a self test routine. From the dissasembly in VTI it appears it puts the
following options in a window:

1) FLASH TEST
2) RAM TEST
3) KEYBOARD TEST
4) LCD TEST
5) IDD OFF TEST
6) LOW BATTERY TEST
7) HI VOLT CONTRAST TEST
8) LO VOLT CONTRAST TEST
9) OSCILLATOR TEST
0) RETURN

The entry point into the routine is approximately 0x259F8C. Does anyone
know how to actually get into the self test?

Wesley
