All of these and a few more came from here https://windows95tips.tumblr.com/ (as far as I can tell)

Thanks for clarification, my unfounded assumption was obviously incorrect. There’s not much info about the AS 3112 type socket but it is, indeed, oriented that way

Both are probably upside down though, because I think the ground pin should be on top to protect against something slipping between the socket and the plug and resting on the pins potentially shorting them

Also for the flip switches down=off is a more common (expected) position

But then again it’s Australia we’re taking about, so maybe upside down was the point
