This is Tetris for the HP48. The program is quite big.

Before loading this program, be sure to pack all GROBs on one line.
Start the game by selecting CST menu and press TETRIS. Exit the introduction
by hitting any key, except ON.
Use the cursor keys to move the falling object.
Rotate by pressing UP-arrow, drop by pressing DOWN-arrow.
NXT toggles display of next object.
RUBOUT exits game.

Flaws: I have no idea of how the original Tetris awards points. If someone
has, please mail me.
