Neo Geo AES 5V DC input circuit schematics ..

I don't believe this exists anywhere, so here's a picture of the OG Neo Geo AES along with the schematics I created of the DC input circuit.

Found this on the neo geo dev wiki:

Seems like there might be a disconnect, i see 1k resistors in your diagram vs 10k on the wiki. The pcb clearly labels them 1k too so the wiki is prob wrong.
