David,

This is a piece of code to wait for the ESC key...

      waitKeyPressLoop:
        tst.w   tios::kb_vars+$1C
        beq     waitKeyPressLoop
        move.w  tios::kb_vars+$1E,d0
        clr.w   tios::kb_vars+$1C
        cmp.w   #$0108,d0
        beq     exit
        bra     waitKeyPressLoop

How does the tios::kb_vars relate to the matrix?  Is this just a reference
to the buffer?

Could you please explain how to use the table in lowlevel.txt with the
ti-92?
