MM57163BR2 Replacement module shown in a Max2 (481) Credit Unit

The MM57163BR2 is a reverse-engineered, drop-in replacement for the original MM57163N display driver chip.

Originally shipped with the Rock-Ola MAX 477 series jukeboxes in 1979, the MM57163 drives vacuum fluorescent displays by processing data sent from the credit unit CPU. This display data is latched and remains visible until a new update is received, ensuring seamless operation.
