  A.K.A. CDC 9762 with a Massbus<->SMD adapter in the bottom. Nice
drives. I powered two of them on a 110V 15A long as I
spun them up sequentially to let the starting surge die down, the
breaker stayed closed. I never measured the actual current draw, but
that sorta says it. :)

  If you have the space, grab 'em! :-)
