*** 128 channels prototype : doing scaling from eval to 128 channels on-going, need to determine ressources used before the tripling method, trigger with window ( limit on how many trigger : 4 trigger in a windows - window size under 1 us ( 400 ns ? ) - can take a couple of MHz ) - TS can be programmed to allow only 4 triggers in the windows - need more processing power for more - trigger are counted, can realign data

***  got NSW ALTIM file of Micromegas design - schematics have a lot of useful notes - 8 chips on small card - Jeff will look at it 
9
*** VMM3 order ok end of January
10
*** plan for december : finish eval readout direct output, processing of 128 channel code
11
*** evaluatiom development board : VHDL code complete, got the 1 gigE examaple, some work with Ben to get it going, C++ software code running on linux ( done at the lab )
