We are running out of things to try for debugging the TC12 controller in
the PDP-12. At this point we are really stumped as to why the TC12 doesn't

TC12 from a laboratory power supply.
We would welcome any ideas that you have.
Don't forget about the other more remote possibilities: cables,
backplane, bad wrap, supply voltages at the actual card(s) for the
mis-behaving channel, etc.
