Hi, there!
Those numbers appear if I turn the Jackpot Key with the door closed. I did it (turn the Jackpot key) when the slot was not working, soon after I bring it at home, with the problem I said before on the Knife Hopper, thinking it was an hardware or software problem...
So, now that is working without any problem I do not need to turn that key again.
I don't know when I need to use that Jackpot key... perhaps if I win the Jackpot to reset the machine??
At least I take off the MPU (the really reason why I buy this kind of machine is not only playing with it but to understand how are working....) to check it (if it was clean and so on). The motherboard is a 10 mHz.
I found a 20c money under the MPU, stuck very close to the electric circuit (!!!!!).....
The battery is OK (seems new one, well charged)... The Game Prom and the Reel Prom are showed in the picture attached...
What's the meaning of the numbers I see close to SP856 "0/1/4/5/12/14" and "1-512"? And the "1-64K" written over the Reel Prom SS6732?
The SP856 is not so easy to find (looking on the web) if I need to change it for hardware failure in the future.
The "SLO" i see written on the stickers over the EPROMs is meaning "SLOVENIA"
... perhaps this slot is coming from the Republic of Slovenia here in Europe where it was exported and used in a Casino?
Thank you again and excuse me for my bad english...
Ferdy
