I got this stuff at an auction for 12 euro. It's an Z80 based measuring
device and a depth sounder transducer. You can see the pictures here:
Although the Z80 based device is on-topic, I am particularly interrested
to find out how to use the depth sounder. It has only 2 wires, so I
assume it is some sort of element that is both an actuator and a sensor?
Has anyone any info on this stuff?
The transducer is a lowrance electronics TTH 1192-8.
