Bally U6 ROM Chip 720-3532 v9.0 (Free Play / 6 or 7 Digit) (SEE NOTES):

Price: $18.00 each

Status: In Stock


Part #: ROMS532
Condition: New
Replacement U6 ROM chip with custom features authored by Oliver Okaegi. This ROM can be used in select older Bally pinballs (see game listing below). It features a Free Play option, and also has support for running 7-digit score displays (see note below). Replaces original U6 ROM part # 720-3532.

Data and instructions on how to make this ROM yourself are available online here, but if you are not able to do the work yourself, you can purchase one here that is ready-to-go (see notes below).

  1. For use only on factory-original Bally MPU boards, or aftermarket MPU boards that support individual ROM chips in locations U2 and U6.
  2. This chip ships as a 2732 EPROM chip, so your board must be set up (jumpered) for 2732 EPROMs in locations U2 and U6 (click here for jumper info)
  3. If you need a corresponding U2 ROM chip to go along with this U6 chip, contact us with the name of your game.
  4. If you need a ROM other than a 2732 EPROM, contact us
  5. For Free Play, set MPU DIP switches 25 and 26 to ON.
  6. For 7-digit scoring support, set MPU DIP switch 21 to ON (OFF is for 6-digit displays). You will also need to install a 7-digit display for each player, and put together and install a small adapter PC board and modify wiring to your score displays (details here)
  7. We do not manufacture or sell the necessary adapter PC board for 7-digit scoring, nor do we provide any help/support for making the necessary modifications. These require a high skill level with electronics experience, or help from an qualified technician.

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