			new test setup was installed in ELL, clon20 runs CODA, VME crate is 'ctoftest1', PC is 'ctofpc1'; scripts are 'ctoftest_start' and 'ctoftest_exit'; passwords were asked if run from 'boiarino', need to fix; will use 'clasrun' anyway

* dvcs trigger

clean AC power for dvcs racks installed, power strips installed, will be connected as first occasion

all discriminators connected to TDCs, all cables checked and good; one trigger-related 34-pair cable seems bad, will be repaired
