An eight coil Superconducting toroidal magnetic spectrometer has been designed for the GO experiment to be performed at Thomas Jefferson National Accelerator Facility (TJNAF). The toroid is designed so that the particle trajectories pass through the magnet insulating vacuum. The magnet is made of aluminum structural components with a copper stabilized indirectly cooled conductor. The toroid is 2 meters long, 4 meters outside diameter and is oriented with its major axis horizontal. This orientation allows its use as an eight fold symmetric focusing spectrometer. The SC magnet has a stored energy of 6.5 Mjoules. The design and analysis of this device will be presented. The plans and status of magnet system procurement will be presented. The RFP  was issued in May 1996.
