This one is one the last pong built so it's quite complete and offers everything a player needs to play pong in good conditions.
The use of the Motorola M-588135 chipset makes it possible to choose a different bat size for each player. The system has even an on/off sound switch (quite useful)!
This pong is the same system as the more famous Nintendo Color TV Game-15. The Motorola M-588315 chipset is indeed a clone of the Mitsubishi Electric M58816P chipset used in the Nintendo system. Games are the same.
