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 required.
