My version seven board has no blown fuses but I looked at chip BA6664FM (located where the reset/eject ribbon plugs in) and counted the legs from the small dipple. Leg 8 (right after the large piece of metal on the side of the chip) when checked with a meter emits a sound. I put the lead on the leg and one near where the screws attach to the board. Now chip BA5815FM located at the bottom of the board leg 19 does the same thing.
Have I done this right? Are the chips fired? Fuses are all okay. System is new and I was putting in a modchip.
