Wingsoffury,
You've taken a real nice photo of one of my pieces of kit there.
That Compass Card Repeater. Do you realize that every one of those on the ship is linked together through a distribution network, allowing every position (from the helm, the bridge-wing, the MCR, the OPS room, the LSO compartment, etc to all have the same heading displayed simultaneously?
Amazingly, it's a WWI piece of technology, using synchros.
The distribution network may be old-school (gotta love tradition) but the gyro that generates the signal is a pretty fancy piece of kit.
