I remember having a friend ask why my mouse connected to a s-video port.
Explain this please.
It's a picture of the ADB ports (for mouse and keyboard, but not only...) on a Mac IIci.
So is this a more classic case of Apple's usual tactic making their things needlessly different to move more product?
ADB slightly predated (and is arguably technically superior to) the PS/2 mouse and keyboard interfaces, but Apple patented it and the only companies that licensed it were those making Mac peripherals.
edit: i forgot, NeXT also used it.
no it's a case of one set of ports being a decade or two older than the other
