Wasn’t 13h disk services? Guess they got shared? Or is it hardware interrupt 13h mapped somewhere else through the interrupt controller?

It was actually IRQ13 -- one of the input pins on the slave interrupt controller. It was typically mapped to INT 75h. I don't know if Windows remapped it.

Should be int 16h I think.

Int 16h was the BIOS keyboard services.
