i'm cleaning this thing at the moment and i'll say that this sure doesn't seem like old soda... it's like loose grease... if that makes sense... and again... it's all over EVERYTHING in certain sections.... if it was a beverage, every part of the sections it's on would have to be submerged in it... know what i'm saying? another data point (or clue) here is the buss assign modules are totally clean. sounding a *bit* more like something that was sprayed all over these parts on purpose.
i don;'t know though! another issue... the molex connectors i sourced for replacement are a perfect fit except for the fact that the holes are a bit smaller than the original ones, making seating the modules next to impossible. gah. pete On May 14, 2011, at 9:52 PM, Ike wrote: > No!
