Take a good, well lit photo of the MB before any paste goes on w/ a modern smartphone at high rez. Print out the photo so it's big enough you can see the labels on the chips. Maybe multiple pages. Fold the paper up and stick in inside the system when you close it up. Then you will always have the image and reference in that machine when you open it. Maybe put it in a ziplock baggie and tape it up somewhere in the case. -andy

Many have recommended that I get thermal paste or heat sinks for my C64 chips. I'm thinking about getting some heat sink as long as I can label what the chip is. Because when I put paste or a heat sink on it, then I don't know what kind of chip is underneath. And as many of you know, there are so many board variations of the C64 motherboard. The chips are put in different places.
