Progress January II - Untangling spaghetti (Patreon)

I've spent 56 hours until now identifying cells and tracing metal in LSPC2-A2 (the main video chip) and things are going smoothly, even if I had to take extended breaks because of wrist and shoulder pain :p
Might have to adjust my desk...

Attached to this post is a collage of the current schematics sheets I "translated" from the die.

For now there are no surprises, no "unused bits" actually doing something, no hidden registers. The only realization is that I could have hardly guessed exactly what was going on inside this just by looking at the signals... Lots of sync and async logic mixed up to work on both edges of the main 24MHz clock.

I'm guessing the schematic capture is 25~30% done.

Also planning on releasing a cell reference for those Fujitsu chips, to eventually help others doing that sort of work on other systems.
