Could someone tell me what the jumpers are on a Bally NightRider using a mpu-17 with original roms. ? Are they 1-2, 3-4 and 8-9. The board is booting up but I'm getting nothing in attraction mode, just a couple lights lit solid.

thanks:
 
That matches what I'm showing. If the board is truly booting up all the way (7 flashes), then that tells you the jumpers are correct. The board wouldn't boot if the jumpers weren't correct.
