Connect 4 - 83 ASM

This is the game of Connect 4, now available for AShell.
The controls are pretty simple:  hit left and right to move the 
piece left/right, and press down to drop it.  To exit the game, hit CLEAR.
To save the game and quit, hit DEL.  The next time you run the game, the 
board will be just as you left it.

Version history:
v 1.0 - First public release
	only 743 bytes!
        2 player mode only
        only 1 round

v 1.0a- AShell release
	contains the same features as 1.0
	only 792 bytes!  (for a lack of libs, I think that's good)

v 1.5-	Now at 965 bytes (I've got good reasons for this!)
	save/quit feature (use the DEL key)
	highlights winning move now

Features to be added:
- 1 player vs. computer mode (I've got a BAD beta on this, but I don't release betas anymore)
- Multiple rounds (best 2 out of 3, for example)
- Linkplay (when I figure out how it works)
- High score feature (to be released w/ 1 player mode... when that comes out!)
- Anything else?

Since this is my first asm game, the source is sloppy, but I've released
it anyway.  Do not redistribute this game without this readme, and do not
change this program except for your own, personal use.  If you do change it, 
do not publish it.  Thanx

bugs, suggestions, tips, money, or anything else you can think of.
