My original online notes were lost due to a window crash.  Below are transcribed notes from a paper to-do list I was keeping in parallel.

*  What we need to do before the preliminary design review?
**  Cabling and crate layouts
***  This should include block diagrams for the entire DAQ system
**  What else do we need to define?
***  We should make a list of all the modules and equipment we need to buy and what we are expecting to borrow from SBS or wherever
***  How will we switch between integrating and counting modes (other than the PMTs); will we need to switch anything by hand
***  What are the requirements and the interfaces to other subsystems
***  Grounding and shielding:  need to discuss and coordinate with Michael.  Star or mesh grounding layout?  Michael has proposed a star layout
***  What are our requirements for deadtime, trigger rate, etc
