Bally MPU tester

in testing phase

MPU Tester connected to BallyFA

Can be used with original Bally/Stern or BallyFA/SternFA

Simulation or port testmode available. Extended 'automated' testmode with BallyFA/SternFA

Simulation of:

- player displays

- controlled lamps

- momentary slenoids

- continuous solenoids

- all switches

Powered by USB-C

parts needed

most parts preassembled by JLCPCB
Adapter PCBs, connectors and ribbon cables needed
display and spacebacker (3D print )

simulation / basic testmode

Default in Simualtion mode. by pushing 'mode' switch it switches between the two modes

SIMULATION:

Display shows all player and status displays

status of controlled Lamps are shown with the first 60 LEDS

Switches can control game

BASIC TESTMODE

LEDs are showing status of each IO ( see text on PCB )

Switches can control game

automated testmode

only working with BallyFA/SternFA and with special FPGA program.

Menu driven:

automated test of all out ports

semi automated test for all in ports

documentation

option DIPs:

1...4: display type

5...6: 12/28/60 lampdriver

7: not used

8: OFF: simulation or basic testmode

     ON for automated testmode
