----- I. INTRODUCTION -------------------------------------------------------

This is an implementation of the classic game of tic-tac-toe for the TI-83
 calculator. It is written in Z80 assembly language, and this distribution 
requires SOS v1.5 (or greater).

Tic-tac-toe requires little explanation. One note is that the internal 
algorithm is intentionally broken so it is possible to beat the computer.

DISCLAIMER : This software is supplied "as is" with no warranty of any kind!
It has been tested by myself and found to work as intended and not
to destroy data on the calculator.  However, there is still a possibility of
unexpected problems with this game, so there cannot be any guarantees
regarding it.  It is possible that it will malfunction and cause a loss of
data on the calculator.  In any case, you are using this software at your
own risk, and any problems it may cause are your responsibility! BACK UP your 
calculator before running any ASM programs.

If you do experience problems, however, you should report them to me as soon
as you discover them so that I can hopefully fix any problems before they
cause trouble for other people!  Of course, I do not guarantee that I will
fix such problems.
