I know for a fact that the Archive Sidewinder uses +5V and +24V, and uses 
the same type of power connector as a normal 5.25" drive. The Sidewinder 
is the tape drive that was used with the PERQ, which is how I came 
across it.

I don't own a Sun 2, but I've heard about the 'odd' power connector, and 
can certainly believe it.
