You could try to get your analog guy to sit down and look at what's in
the Polaroid unit. Don't make any rash assumptions - it's like the
comments found buried in the SS system legacy code ('Subtle!'). I can't
really tell you what to do (what I've done belongs to Time Tech) but I
can tell you that just 'cause it's simple doesn't mean it's easy. If you
look at it right you'll get what you want.
