DESCRIPTIONuturn provides the functionality of IOA (not currently supported) as a
bridge from the Runway bus (see runway(4) for more information) to GSC.
Modern systems, based on the PA-8000 and later 64-bit CPUs, use the
U-Turn version, whilst earlier systems, based on the PA-7200 CPU, used a
different version of the chip called U2.
