Sadly I haven't been able to catch any streams recently but I saw you made this repo, I had some time today so I opened it up and had a look for fun but ended up finding a couple minor things to improve as described in the commits.
PCB DRC now passes with only warnings for ISA card edge being too close to edge cuts (likely just add exceptions for them if you're not chamfering the ISA PCB edge).
I didn't find any major issues with the schematic but I could only look for basic stuff without understanding how it actually works.
Also, well done on getting this PCB so close to the original!
