uturn 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.
