Taking a look at some other Naomi game manuals I've found a similar thing in ClubKART (page 14).
As you can see while SLOT1 show 0000, SLOT2 show 8000. Now, taking a closer look at the cabinet pictures, it seems that this cabinet does not have a Coin Door 2, so this makes me thinking that the number 8000 means SLOTx disabled.
Can someone confirm or deny this supposition? And then tell me how to change state from 8000 to 0000?

Thank you a lot,
