Re: preampboard and shaper test

["Fernando J. Barbosa" <barbosa@jlab.org>]

Hi Gerard,

    Because we have a limited number of ASICs, I will send you the 
preamp card, interposer and cable that were destined to be sent to CMU, 
unless there are objections. You can then take all these items with you 
to CMU for tests with the CDC.

Regards,
Fernando
