[Solid_cc] MAROC as default readout?

[Zhiwen Zhao]

Hi, Michael

I think it maybe possible to borrow some MAROC for the beamtest from 
INFN and/or jlab
We did this test with 4 MAPMT at Fermi lab in May

Also I don't know if a simple summing board without proper amplification 
will work for you test with 1 or 2 p.e. at trigger

Let's meet at 1:15PM with this line
