Description

6/7 digit Pinball display for early Bally games

Pinball machines in the 80s used high voltage seven segment displays to show the scores for each player. After 40 years of use these displays are often broken and original replacements are hard to get. My display provides a plugin replacement for these old displays. It comes 99% preassembled, only a few header pins need to be soldered manually.

It fits for allmost all 'Bally' pinball machines produced between 1977 and 1985.

Features:

- 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.
