Hi,
My C64 boot up with wrong character and with garbage message on the screen.
I use Diag Test Cart to diagnose it, it says "NGZERO 0002E02". Because Zero Page memory is internal to the 6510, does it mean 6510 MPU is failed?
I tried replaced all 4164 RAM chips, but it didn't change anything.
If 6510 is failed I should buy one to fix it. It's diffcult to get a 6510 now.
Thanks!
