I started to design a pong system using only discrete logic, but to reduce size and complexity, I decided to use GALs(not a microcontroller just a programmable and array). One of the differences in my system is that im using a 7x5 matrix for the game field and 1x7 matrixes for the paddles.So far i have designed the the paddle controller and ball movement and in currently working on the logic behind the rules of the game (so far i can make the ball bounce in a different direction depending on where it hits the paddle, and bounce off the limits of the playing area). If anyone is still interested i would love to exchange notes and see what we could come up with

Ps English is not my primary language so I apologize for any grammar errors

 

No errors in grammar or usage - just dates. The thread is well over a year old - http://forum.allaboutcircuits.com/showthread.php?t=16541&page=3

Still, you may find someone who is working along similar lines.
