hello all ,
I ve read many posts here about the 50/60hz switch , but no one seems to have the same board than me , or i didn't understood all . I' have no good knowlege in electronic so i prefer asking before to screw up anything.
i would to switch my system 50/60 hz ,
and it seems it s not a V-7 or V-9 board , it s pretty bizarre board:
-model 2 ,
-with a separate board for joypads entry,
-pin 79 of the VDP1 chip leads to a litle soldered jumper (or whatever it is?...) called R29 (it s written 104 on it) which itself leads to JP1 (there is no JP2).
So i wonder what i have to connect to +5V ?
-the R28 hole ?
-directly the 79th pin of the chip ?
-or simply connect the two JP1 plots together ?
