Are you working your way up through the eras of CPU's? How far do you predict you'll be able to get? (Ps. Thanks for all the awesome insight you've shared)
It's sort of random. My intent is to focus on the 8086, but someone asked about the 386 so I looked at that a bit. Then I saw the Navajo Pentium rug in a museum so I figured I should look at a real Pentium to compare. And then I wondered if I could find the FDIV bug. So one thing leads to another. I don't think I'll be able to go much beyond the Pentium with an optical microscope, though.
