Someone took the original schematic of the 100 and replicated it with a
kicad high quality rendering. Should be able to replicate the board with
all that work completed. I have some thoughts.

I will be playing around with it while I relearn kicad. It's been a
while but having fun.

I'm glad the open source solutions are popular vs the old school
expensive suites running only on mainstream os.

kicad works on both my old, decrepid laptop and my raspberry pi 500.

Got to research the BOM for the 100 and see if they all have modern,
backwards compatible equivalents for the chips.
