I fixed the mistake with the #MOSFET and didn't even have to turn it on its back. I lost one in the attempt to bend the legs.
Now the power gets cut when it's over 5.53 Volts. Both LEDs turn off then, but fixing that would require cutting traces underneath the #comparator, which I don't want to unsolder again.
Time to attach a cable and use it for protecting my #Commodore #C64

Today my new #PCBs arrived. The first is an adaptation of Stefan Wagner's #C64 Power Guard: https://oshwlab.com/wagiminator/c64-power-guard
I changed some components to what I had available. Thanks @aislerhq for manufacturing them.
Only I messed up two small details. The second #comparator is backwards, so the error #LED is practically the same as the power good LED. And I also put in the #MOSFET backwards. I'll try to mount it on its back and rotated tomorrow.
