IMPORTANT NOTES FOR EARLY BALLY & STERN ROM CHIPS:
  1. Replacement chips we sell are for original Bally and Stern circuit boards. They may not work on some aftermarket replacement circuit boards.
  2. Your board must be jumpered and/or modified to use the type of chip(s) you are installing, otherwise the board will not work. (Click here for more info).
  3. Before ordering, you will need to determine the type of chip you are replacing, which should match what your board is jumpered for. (Click here for more info).
  4. Order the type of chip that matches what your board is jumpered for. (Click here for more info).

    We are not responsible if you fail to order the correct chip(s) for your board. If you have any questions, feel free to contact us.
The above software is provided as a service, but is not being sold. Price above reflects the cost of the service to provide the manufacturer-owned software on game-compatible media, and installation instructions for the software that comes on the media. We do not sell or own any manufacturer software.

NOTE: No returns on ROM & Software Updates - all sales final.
