Quoted from swampy:HI RFM experts. I am trying to get my head around an issue with a game here in the desert . For the record I am reasonably experienced with pinball repair but far less so with the P2K platform.
Game is running a Nucore computer. On power up with a normal boot there are no playfield lights, no coils will fire, no start button flashing etc. PF is essentially dead. Game will sit there in attract mode with the computer booted normally but PF is dead.
I have checked basics like cables etc but not sure where to go from here. Are there any common areas or faults I should look for? Perhaps a driver board issue?
Thanks all.
My PC will lose the setting on a CMOS battery failure (or low battery or even a boot sometimes) the default BIOS settings on the system has the bidirectional parallel port and/or BiDirectional disabled - the PF will be not responsive in this mode - enabled ECP Bi-Directional (each mother has it own name for this setting - SPP recommended. (All modes will work EPP, ECP ) Default 0x378/IRQ7) try a setting on the parallel port in the BIOS settings of the PC the PF will become active when next started, if not try another. Loading the BIOS Defaults in my PC the PF will become unresponsive.
