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

The MM57163BR2 is a reverse engineered drop-in replacement for the original MM57163N.

This is the display driver chip that was first shipped with the Rock-Ola MAX 477 series of Jukeboxes in 1979.

The MM57163 drives the jukeboxes vacuum fluorescent displays with data sent from the credit unit CPU. This display data is latched and shown on the jukeboxes displays and is only updated when a new display data is received.

Rock-Ola Techna Retrofit Display Kit

by

This new display board is a direct replacement for the Rock-Ola 53170 board found in the 480 Techna, 476 Grand Saloon II, 484, and 488 Jukeboxes manufactured by Rock-Ola. The original vacuum fluorescent displays fail and replacements are not easily obtainable. The new board uses LED displays and is a direct replacement for the vacuum-type display board. Additionally, the new display board can still be used with the original display driver IC (MM57163N) located in the Profit Setter Module.

In most cases, the MM57163N display chip is also faulty and for this reason, it is included in the Kit. (The MM57163N replacement is also available separately)
