Making this its own post... I originally attached it to this post -

Will continue to update this post as more information becomes available.
Some BB2 (?) and BB3 games are made for certain cabinet types, limiting those that have a singe game cabinet, yet the backplane is the same for BB1, BB2, BB3, Blade, Blade2, Gamefield, and some others. The only difference is setting various pins on J14 of the backplane.
Pin 1 to ground makes unknown cabinet
Pin 2 to ground makes unknown cabinet
Pin 3 to ground makes Gamefield
Pin 4 to ground makes GFxDv1
Pin 5 to ground makes Blade1 .. (not sure if it is Blade1 or Blade2)
pin 6 to ground makes sVAR1 (value 11)
pin 7 to ground makes video change
pin 8 to ground makes unknown cabinet
pin 9 to ground makes unknown cabinet
pin 10 to ground makes CPU Logic Box OK
Pins 4 + 5 to ground makes cabinet type S32 (Value 9)
Can connect these pins to switches that go to ground to make it easy to switch.
Depending on the monitors you have, your mileage may vary
From what I have been able to gather, here is a table of cabinet values -
0 = BBxD
1 = BB2e
2 = BBS
3 =
4 = Blade 1
8 = Blade 2
9 = S32
10 = S23
