Yeah. And if you press <>-[ON], or [2nd]-on it will crash ... and you
can't turn off
the calc...

Read the ports.txt file. I forget the address, but you have to write
something to some bit of one of these 32 registers before you can write to
memory below $120.
Oh yeah! DON'T end your program with the int vector pointing into the
program. The TI-92 dynamically re-arranges it's memory... so, some time
later, your program might not be where you left it, and the vector will be
pointing to nonsense.
