[Halld-online] Adoption of front-end board data format

[Elliott Wolin]

Hi,

Having 1) sent out my original note (see below), 2) talked with many of 
the relevant parties, and 3) having received no feedback to the 
contrary, it is my understanding that all involved agree:

a) To implement Dave and Ed's VME readout format in their modules.

b) The modules will be ready by the time Hall D needs to read them out 
(start this summer).

If you do NOT agree with both of these please get back to me ASAP, as we 
are proceeding with online and offline programming as if this is the case.

I note that this VME format may differ from that used by some previously 
released modules (e.g. discriminators), but that having a uniform format 
across all modules is more important.

Thanks,
