Can someone with a TM verify a couple things for me?

- numbered (past) and alpha (future) targets - are any of these supposed to trigger in pairs. I.e., when I hit a, e is also going out. I'm guessing it's bad diodes on the switches, or possibly transistors on the board, but before I spend a bunch of time on it I wanted to verify it's not designed to do that intentionally.

- what lights the orange special?

- what triggers the 5-10-15 multipliers? None of them are lighting currently, but I'm not sure the multipler is being applied either (hard to tell when it's not lit to know it SHOULD though).

Thanks!
