Hi Im trying to fix this Commodore 64 but so far no success. When I power it up I get a line on screen (look at picture), after about 3 minutes the chips are slowly getting worm except for the PLA,SID and Kernal they get hot but just enough so that they can still be touched, i probed with my scope pins 1 and 39 on cpu and the clock seems fine ,how do I proceed from here I am suspecting the PLA but dont have another Commodore to test it I heard that I could test the chips using a arduino but probably would need a code for that.
