Sort of on the same topic, I'm trying to figure out a way of modifying a
Polaroid sonar unit to act as a beacon.  The problem I've discovered is
that in order to have the receiving sonar unit "listen" for the pulse from
the beacon the receiver must bring the INIT line high, thereby generating
an unwanted pulse.

Anyone know of a hardware hack to allow the unit to listen only?
