Notes
PCB is marked: "seletron 78", and "10-10500" on component side
PCB is marked: "seletron 78", "10-10500" and "110778" on solder side
update 20140630: Kirmo dumped the PROM
update 20140107: Kirmo send the following: "Crystal frequency: depending on jumper (2jk): 4MHz , 8MHz , 16 MHz
Main clock frequency : 4 MHz (if an 8 or 16 MHz crystal is used, then the 74LS74 (3J) will cut the frequency down to 4 MHz)

update 20200410: just found a second PCB for the same game. There is a small HW modification, with a small piggyback PCB addded.
Redumped the PROM, and found a different content; I strongly suspect that previous dump from Kirmo was bad.
