The original Firepower used the momentary contacts. The continuous contacts were connected
in series within each bank, and connected into another place in the matrix. This gave the software an extra piece of information that all the drops in a bank were down. You can connect your drop switches this way, but its extra work that is not necessary. Here are the switch positions:
“1-3” drop target series – switch 20 (Green-Orange/White-Yellow)
“4-6” drop target series – switch 24 (Green-Orange/White-Grey)
The “10-point” switches are wired as follows:
“1-3” drop target standup – switch 55 (Green-Violet/White-Violet)
“4-6” drop target standup – switch 52 (Green-Violet/White-Yellow)
When wiring switches, note that the White wire is connected to the anode of the diode (side WITHOUT the stripe), and the Green wire is connected to the switch terminal NOT connected to the diode. Refer to another switch on your playfield as a guide.
