Cable Color Coding

["Michael Raphael"]

I was out the other day with someone who was recording MS, and their
cables were color coded, so Input 1 (cardiod) was red and input 2
(figure of eight) was Green.  I was told that this was based on a
Nagra design.  It struck me as odd at first . . . .   Has anyone seen
this kind of orientation before?

Thanks,
Michael
