QTY	Type	position	status
1x	custom IGS011 (FPGA?)	u24	not dumped
2x	PAL16L8ACN	u17,u18	read protected
2x	PALTF22V10B	u15,u45	read protected
1x	ATV750	u16	socket is empty

1x JAMMA edge connector
1x trimmer (volume)
3x 8x2 switches DIP

The PCB is perfectly working, empty spaces and empty sockets are clearly intended to be empty.
