- LED, no high voltage
- can be dimmed
- dot enable/disable
- 6digit and 7digit version available
- 7 digit displays can be used in 6digit games (together with 7digit bootleg rom)
In most cases for a 'standard' Bally ( 4 Players) you will need four 7digit and one 6digit display.
how to order your Bally display
Have a look to the PCB documentation section.
Needed Gerber Data, BOM and Component Placement List (CPL) you find below.
In addition to the preassembled board you need the components from the shop carts and these LED digits (or similar ones, make sure you order 0.8" digits with common cathode).
New! Version 1.4 with SMD Capacitor and (optional) preassembled red LED displays.
If you do not have a 3D printer on your own, the display baffle on the left can be made by JLCPCB 3D printing service.
My 7digit displays can be directly used to update 6digit Bally pinballs to 7digit together with a 7digit bootleg rom, as described by Okaegi on his website. The 'little PCB' described on this page is already integrated, no need for new wiring, its just 'plug and play'!
You need to configure the display by setting three jumpers (or solder bridges) as visualized on the PCB!
There are two modes:
- '6digit' mode -> for a game which has usually 6digit displays, plus you have the mod rom installed
- '7digit' mode -> for a game which has 7digit displays
With BOM & CPL provided you can choose between preassembled (red) LED digits or decide to solder & purchase the LEDs on your own.
New: For the version with preassembled LED digits you can also do a 'one click' order at PCBWay with the link below! See also my review with a comparison of ordering at JLCPCB & PCBWay.
