Project 'on hold' at the moment! If you plan to use LED displays with your Gottlieb game have a look to my LED replacement und to my System80 power supply.
LISY80 LED is a modified LISY80 board. A 5Volt 5 Ampere Power Supply is included on this board in order to have enough power for the LEDs. With LISY80-LED it is possible to easily exchange the Gottlieb Displays on system80 and system80A with modern LED Displays. You need the LISY80-LED MPU which also includes the power supply ( the original Gottlieb power supply 'A1' is no longer needed) and a set of LISY Displays ( DISP80 & DISP80S)
Unlike any other solution on the market with LISY80-lED you do not need add new wiring! Just remove your power supply, Exchange your original MPU with LISY80 LED and your Displays with DISP80 & DISP80S an d you are done.
See Pictures below. LISY80 LED is currently in testing Phase, first prototype is running.
