Well, I'm at a stand-still with this repair... I got some more RAM chips, but I started thinking that I really have no reason to believe the new chip I installed is bad. These weren't yanked from a dead machine, these chips are NOS. Not that it's not possible for a NOS chip to be bad, but I wanted to make sure there wasn't anything else I was missing, so I went back to the Dead-Test manual to see if there wasn't anything I overlooked, and came across this paragraph that I hadn't noticed before: "Some RAM failures may cause the Dead Test to display incorrect results. The majority of these will display a One (1) Flash Code (which is the code I started getting after I replaced the cooked chip) indicating a Defective Data Bit . If the associated RAM is replaced (which it was) and the results remain the same (which they have), the real failure normally turns out to be a Defective RAM IC associated with Data Bits [0 or 1]. Flash Codes are normally an indication of the Data Line being held either high or low. Although this is usually caused by a defective RAM IC, it is also possible for any IC associated with the Indicated Data Line to be at fault." Without an oscilloscope, the only option I seem to have is to start replacing the rest of the RAM chips until it works, and hope that it's a RAM chip and not a processor. I'm not really hip to that... Nor am I hip to investing in an oscilloscope, for this one task. If anyone has any ideas, please feel free. I also took a picture of the traces that had some of its insulation worn away. I don't think it's causing the problem, but I thought I'd throw it up here so that more experienced eyes can have a look at it.
