    • can put documentation for other control
    • (new) ROC17 F1 data - data left at sync event - seems fixed after fixing busy cabling
    • (new) hodoscope no data in some events - seems fixed after putting busy from distribution board
    • (new) HCAL ROC17 crash / shutdown
    • (new) V1190 stuck at prestart - went away after switch to external clock - maybe bad connection
    • (new) setup network port for UVA chamber testing in EEL 125
    • (new) deadtime ROC17 HCAL
    • (new) deadtime ROC5 hodoscope
  • Hall was cleaned - fibers left and table left
  • Helicity board : 2 avalaible
  • F1 : need to test high rate
  • could increase threshold - window width 1000 ns maybe - need to be optimized - 40 ns - no remote threshold right now - on camac - might be able to control

288 channels = 18 NIM modules
