AT/PS2 use the same protocol, which allows for "unlimited" keys held down. Similar to the Amiga, they send keydown and keyup events separately. XT also is a keydown / keyup based protocol, but it is subtly different in signaling to AT/PS2.
USB only allows a few, if you use the standard USB classes.
