Williams System 7


Some time ago we have purchased a Black Knight and a Jungle Lord, both without any electronics inside. Those pinballs are Williams System 7 series, usually equipped with 4 7-digit numerical displays and one special credit display (2x2 digits). Based on our previous good experience with LED display developments is was logical to make a LED replacement for these, too. This is how it looks like, put inside a Black Knight Backbox... (ok - it is a Jungle Lord backbox with BK backglass ;-) )

The next picture shows the most important piece: the LED driver board, which is mounted on the backside of the backbox door:

Ans finally this is the whole display set:
