the part that concerned me was the name of the DRO, magnetron. wasnt sure
if it used magnetics as opposed to the optical, so i dont know if it would
be ttl or some analog signal or what. and my oscilloscope was through a
flood and i dont even know if it still works, i havnt even cleaned all of
the mud and gunk out of it caus im afraid of how it'll look in there. and
without a scope to use, i dont really know how i should start tryin to
figure it out.
