It doesn't have every feature we might eventually want, but I tried to clean up the logic for the trigger for the beam test and make it possible to turn on and off triggers without unplugging anything and set and forget delays. I tested all the inputs and outputs on the bench and used equal length (working) cables everywhere. You can turn triggers on and off by pushing buttons The one thing it doesn't have that would be nice is the ability to mix triggers, although I would think we'll mostly take a single minimum bias trigger, and then just tag events with hodoscope, cerenkov, and scintillator bits, although it might be nice to mix in cosmic or LED triggers, although maybe simple and straightforward would be better.

Abhisek and I will test this a little more, get a fan under it, and tomorrow hopefully replace the rats' nest that's grown up.
