The most likely usage of the 4-pin with center two clipped is for a
speaker. The 4-pin with one clipped is likely a battery connection with
+5vdc on pin-1, the clip as a key at pin-2 and pins-3&4 at ground.

No good guesses on the 9-pin connector, though it might be a header to
run a cable to a keyboard connector on the passive backplane.

It should be OK to plug it into a passive backplane, but I'd be a bit
reluctant on a normal AT motherboard.
