FW: Chess on the TI 83?

        I think this prospect seems impossible at the moment, a good starting
point would be to program checkers/drafts which only has a few
possibilities for each move, the calculator will be capable of this and
would be a good measure of whether it could handle the chess game.  It
would also probably be the only Human v Calc AI game availiable for this
format and would have great popuality.  I am only 15 tho' and can't be
expected to program in ASM, Yet.

 I didn't deny the possibility for a chess game. I only said the difference
from a
coputer ram and a calc ram was that the calc both stores progs and
RandomAccessMemory' the Ti-ram.
And of course you can make a chess prog at 27K.
Do we really need the calc to do 6 moves with all the pieces??
If you want a real challenge chess you should go for computer chess.
There are 16 pieces which may be moved, and for every piece wich moves,
there
is 6
different moves for ALL the other 16 pieces. If it thinks 6 moves ahead (3
for
each side) that would be 16^6 moves
= 16777216 moves. That is all the possibilities in the next six moves. My
math
might be wrong, it's sunday..but you get the point, 6 moves ahead is a lot.
BTW: are there any programmers who would make this game??
