Notes

PCB is marked: "LC" on component side ("LC" is the Italian for "Lato Componenti" which translates to "Components Side")
Differences to original are:
1) only 2 PROMs instead of 3
2) test screen has Italian wording instead of English

This board comes from the same (unknown) manufacturer as Mouse Trap (version 4, bootleg)
