Williams System 7 and 9 display set
Question: After installing the PinLED display set, the last two digits in every player display do not work. What can I do?
Answer: Set all four DIP switches on the display controller board to the other position.
This Williams display set was also used for bowling alleys. There 6 player displays are controlled. But then only 5 digits, which means that the last two digits are omitted. With the pinball machine there are only 4 player displays, which then have 7 digits.
