I purchased a Wonderboy in Monsterland PCB and a system 8 adaptor.

When i put it into my jamma cabinet, the red LED lights up on the board, but nothing else happens.

Any advice would be appreciated
 
Check the cpu chip and the crystal to make sure nothing looks wrong (pin out of socket, in backwards, wire broke on the crystal, etc.) if it's not showing anything the cpu might not even be booting up.
