IBM apparently used up their surplus of them on microchannel RS/6000s, 
I've got a bunch of them from RS/6000 machines.  Unfortunately, they're 
pinned out like PS/2 drives (power on the 34-pin ribbon) instead of a 
separate power connector, but it's not terribly difficult to make up an 
appropriate adaptor.

Send me mail off-list if you want one.
