	2. JLAB discriminators: first test was conducted using 1877 TDCs (500ps resolution); threshold dependence is linear, with dependence is 'almost' linear; resolution from trigger output is about 2.26ns leading and 2.36ns trailing edges; TDC output shows 530ps which is TDC resolution, will use high res TDCs to measure it; test input and scalers to be tested as well; delay from input to trigger output is 75ns (and can be decreased), delay to tdc output to be measured		2.

 . Next run preparations:
-* BONUS readout: 3 PCs with Linux, 3 TI PCI cards, 3 RORCs, 6 crates, 26 FEC cards; new PCs will be installed on North SF, probably in DCHV rack on the floor; they will be connected to the branch instead of tage, tage2 and tage3
