Notes
PCB is marked: "937" and "lc" on component side ("LC" is the Italian for "Lato Componenti" which translates to "Components Side")
PCB is marked: "001" and "ls" on solder side ("LS" is the Italian for "Lato Saldature" which translates to "Solders Side")
update 20200112: comment from Osso: "this is a year hack: it has 4 different bytes total, 2 to change 1995 to 1997 in two places and 2 corresponding changes to fix the checksum"
