hi,i've got a pal saturn!it's first model,with two leds power and access!
i opended it and i found that the power board is not connected to the upper side of the chassis and that the joypad ports are on another little board!
i found the pin 79 but it doesn't continue to any point,it only goes in the board and if i look at the other side of the board i can find jp1!!
yes only jp1,there isn't jp2!!!
i tried to connect the two sides of jp1 in this way:
jp1 *--------*
but when i power up my saturn i only see black and grey lines on the screen of my tv!!
i disconnected the two sides of jp1 and everything works fine again!
the i looked for other jp points but there are only jp6 and jp7,nothing else!
they are connected like this:
jp6 * * *-------* jp7
now i konw that i must cut the pin 79 and connect it to a switch!
i must connect the switch to 0v and +5v too!!
THIS IS MY PROBLEM!!!!!WHERE ARE 0v and +5v?!!??!
please how can i find them?
what do i need?a voltmeter?is every point good to do this?
are jp 6 and jp 7 good to do this?
please help me i want to play games at 60hz!
thanks a lot!bye! |
