Hello all,

I am having some trouble with my Black Knight 2000 not registering any of my drop targets.

I recently had to pull the Interconnect board and replace the special optos to fix a random tilting issue when hitting the left flipper. Since I was replacing one, I went ahead and changed them all out, and had them socketed to facilitate faster replacements in the future.

Do the drops in BK2K operate off of these special optos?

The game otherwise tests 100% functional, including the 2 other switches on the common driver. As an extra test I even swapped in my spare system 11 mpu with no change.

I also checked each opto on the drops and had nothing show up in the switch tests.

Any help would be appreciated, thanks!
