    2. Mac II, Quadra & Centris

      Just think, having a Quadra 950 in 1992 would be like having a Mac Pro today… except with more slots, more expandability, and on-board SCSI!

    • Yes, its heatsink was actually discoloured.
    • Thank you, I will have a look and swap out the BUD again. 
    • You are opening a huge can of worms with that one. The debate on whether that is good and works, is harmful because the water is not deioniozed, or the toxins from the board will slowly kill you as you consume them from your plate in the dishwasher is raging in a never-ending battle on here.
    • Yeah, I think probably just a broken trace. I think it's possible that this wire was run at the factory... but that's just a guess.
    • Ok so today I did another run at the Mac II, discovered a couple of extra traces that were cut (some are quite subtle!!) near the power switch. I ended up cleaning the thru hole cap holes with the tiniest drill bits and that was a lot less stressfull than all the other attempts and methods I tried. I don't know what I'm doign wrong, but no amount of heat. So I've now reinstalled the big caps, and the battery holders. I still need to do another inspection, then wil be re-solderring the SOIC14's, then I have a couple of extra patches to add for traces that are cut /under/ these SOIC footprints, (I don't put the patch wires now as I'm going to put hot air in the area). So I'm getting there. I had a close inspection in the RAM slots and it all look clean. My worries are the areas near the Sound Chip and the GLU, and I can see a couple of traces that look 'dark' go /under/ the ICs   One thing: I've heard you can put the mobo thru the dishwasher to clean all the rest of the gunk that is under bits and connectors. Does anyone has done this? ie short cycle, no soap, low temperature than air compressor, then let it dry for a week, or bake it?
