	1. BONUS RTPC DAQ		'''BONUS RTPC DAQ'''

	BONUS DAQ was discussed. We'll consider fiber optic controller instead of USB one, new receiving card will be in PCI-X format. We need to buy electronics from TPC group and ALICE DAQ group. PCI card will come with Linux driver, we need to provide optical signals (trigger etc) and probably slow control over Ethernet.		BONUS DAQ was discussed.

	- clonmon, root_server		- new 'clonmon' machine was installed, it has apache server opened from outside of jlab. First version of the new component 'root_server' was created and is running in test mode creating root files. Those files has the same set of histograms as fast online reconstruction and can be viewed by Carrot apache module.

	- new clon10, old clon10 to ELL		- new clon10 machine was installed, old clon10 was renamed to clon00n and will be decommission or moved to ELL to serve as test setups server
