1. JLAB discriminator board prototype was tested by Sergey P., latest test was with triangle pulse, all results obtained with rectangular pulse were confirmed, although threshold slope changed slightly: 0.235 (triangle) and 0.263(rectangular), Ben will check it, it must be exactly 0.25. Passive splitters were used. Temperature test still to be done. Board will go to Ben for more tests and changes. When ready, will order 5 boards. If Sergey Kuleshov's people will be involved in testing and production, we'd recommend to produce test board to run tests automatically. Will discuss it when people from that group will be here next year.
2. eg6 run reached production stage after about month of commissioning, number of DAQ problems were resolved. Main problem was related to the pipeline regime in TPC readout, it was fixed by CERN/ALICE personal due to Raffaella DeVita efforts.
