Nice to see back to basics. I'm tempted to do something similar with valves (tubes) as a spin-off from my work at @tnmoc.bsky.social on EDSAC.

I too would love to get a schematic and build this if possible

What a wonderful project! Care to share schematics / boards / bom? I would be happy to redraw in KiCad if not already and share. Would love to frame this and hang on the wall and gift to a few friends too.
