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
