Needed for magnet test
Total number of boards (4 available now) and optical receivers (to buy now)
LVDS external CLK (from TTC)
VME CPU for local access (Status and Control registers, configurations, local data readout)
S-link readout hardware (transmitter)
More tests in Legnaro if ROS-8 will be used OR
tests in Madrid if final ROS will be used
