I was a bit concerned about having the EIO interface flapping
around loose and breaking something so I made myself a
"ruggedized" enclosure for it with all of the inputs & outputs
brought to 1/8" jacks, the wideband inputs coming in on a plain
stereo cable from the LM1 and looped through to two mono,
separate jacks (like for running the LM-1 analog gauge) and the
two DB-9 connectors are also provided some strain relief (against
off-axis forces anyway) by the case. I got all of the parts at
Radio Shack.
It's a bit bulkier but now I don't have to "baby" it any. Better
for a shop setting (or just plain old carelessness).
