I have the Tron Free play eproms for sale.
This eprom replaces the eprom at D2 and allows you to have the free play option on your tron arcade game.
Freeplay mode is turned on and off by setting switch 4 on the dip switch set SW1. When switch 4 is off, the game behaves as it always did. When switch 4 is on, Freeplay is activated. The game will display the word FREEPLAY where it formerly showed the number of credits and PUSH 1 OR 2 PLAYERS where it used to say INSERT COIN. The game will still run through attract mode to help avoid screen burn-in. Pressing one or two player start will start a 1 or 2 player game without any credits needed. If you have your "Allow Continues" dip switch set, when it comes time to continue, you can do it without adding any credits.
Installation of the freeplay chips requires replacing one EPROM on the CPU PCB (the middle one). No other modifications to your PCB or cabinet are required.
Locate the EPROM at location D2 on your CPU board (the middle one in the main three-board stack) and make note of the date and let me know what the date is before buying
30 shipped.
