Konami 007121 tracing progress II (Patreon)

More progress. My buggy Python "ERC" (Electrical Rule Checker) script says that tracing is nearly 70% done.

The green cells are fully connected, the yellow cells are only missing one connection, and the white ones are missing more than one.

For some reason, their placement causes 3 distinct horizontal areas in the chip: A top one containing most of the DFFs, a middle one with many small cells such as inverters and 2-input gates, and a bottom one full of NORs and latches.

I've also started putting my 3D printer to good use, by printing an OpenFlexure positionning stage (second picture - more infos: https://openflexure.gitlab.io/).
If this works out, it might save me from having to purchase hundreds of $ worth of equipment to finally automate scanning on my microscope.

The next post will be the final, paid one for this project. I'll provide the link to all the files, and updates regarding the microscope.
