Others

1x 28x2 JAMMA edge connector
1x 10 legs connector (MOLEX 10P) connected to small daughterboard with double JAMMA edge
1x trimmer (volume)(VR1)
3x 8x2 switches DIP (SWA,SWB,SWC)
1x trimmer (unknown, on small modification PCB)

Notes

small modification PCB is connected to main at resistor-net with 4 tiny cables (all of them cut off)
connector PCB is etched "LATO COMPONENTI S.E." on component side
main PCB is labeled "OGA", "O.K" and "9453" on component side
(1) the chip is unmarked, but I strongly suspect it to be a 16C57 due to the fact that a check on my programmer gives "bad contact on pin 3,5" which are NC on said PIC


update 20220514: completed dump (but for 1 bad MaskROM)
