The RICM Learning Lab was nice and cool today so we spent the afternoon
chasing the "LGP GP=GPC PRESET" in the TC12 LINCtape controller. With a
logic analyzer connected to lots of the TC12 signals were were able to
chase down the signal that is causing the fault. We are now not sure if the
signal behavior we observed is the correct behavior, and there is a fault
elsewhere. More debugging time and more studying of the documentation is
