  • Made for a golfing game, we are figuring out how it works.
  • There are two parts to the display unit:
    • A control board which stores a small program that runs the display
    • The display LED Matrix.
  • The connection between the control board and the LED Matrix is a 16 pin plug, we have traced the 16 pins to their purpose.

Control Board

Has a motorola CPU, various logic chips and two EPROM chips, the one EPROM chip is an AM270010-12000 00110M5M E.

LED Matrix

The LED Matrix has 2 rows of LED matrix displays driven by 8-bit shift registers.

The LED Matrix units are Kingbright TC20-11EWA PB, the 8-bit shift registers are TPIC6B595.
