Case International 5130 - xsashox - 10-03-2023
Hey guys,
Helping out a friend here. Its a Case International 5130 - was told its 1994, obviously not. Plate says 91’.
Expected to find 93C46 inside… found actually nothing. Does anyone know how this actually counts hours and how to get them back?
On the board only CS-8190 and KA2904.
Pics attached. Thanks

Ok guys for anyone who needs it;
This clock can be reset by shorting out some pins on the backside; after that you can solder a wire and generate a pulse to get it to "count hours".
Right now i'm using UPA to generate 500kHz pulse generator to bring the hours up. Anyone got any idea how to get it faster using DIY stuff? Esp32 or Arduino?
