          + Plan: fill with water, leak check
          + schedule very tight
  * Preparations for Run
      o long list of items from Tim
          + cryo box on magnet almost empty, but refrigerator started
          + solenoid HCO on Wed.
          + vacuum by 8/17
  * Sergey
      o old and new file servers in hand
      o waiting for Sascha's work to complete before switching
  * Sascha
      o last week cosmics taken
          + new ROCCDC1 did not work, reverted firmware to old version
          + ran BCAL cosmic trigger
      o working on new firmware for DIRC SSP
          + firmware like Hall B RICH
          + having library compatibility problems
          + trying to unify libraries with Ben Raydo
          + trigger SSP needs modification
      o ready to start the run
      o DIRC: special crate, optical connection there
          + lacks SSP read-out
          + LED system going in, CAEN 1495 used to drive LEDs
          + will be ready for run
      o CompCal
          + 10 FADCs in crate, connected to read-out
          + Needs connection to trigger system, Ben will do that after
            finishing DIRC
          + CAEN 1495, LED system installed

      o may have to re-arrange applications, alarm server was running there
      o David: seems really dead, two PSs for redundancy and neither works
      o gluon49 is also dead, but that happened a long, long time ago
