Can someone clarify and expand on my thinking here. I understand that most 486 mobos without onboard com/lpt ports send -12v to the isa slots. And it isn’t used for anything else. Yes?

It shouldn't be used by anything else but COM ports if they're onboard.

Yes. That matches with my ongoing studies of PC architecture.
