The bearing conversion is done in-game. Our sonar bearing points to MOT.
Hey, did you see those inputs for distance between perisope and torpedo tubes? The inputs for torpedo speed? There are all kinds of fascinating things going on there with all sorts of interesting implications. For instance, they could have actually transplanted an American TDC into a little bitty U-Boat and made it work in pretty short order! Or used the same TDC in an S-Boat or Fleet Boat.
The TDC was built into two cases, side by side, so they could fit through the hatches and it could be installed without taking cutting torches to the hull.
But what really interests me are the photos of the difference and trigonometry modules. Yikes! They were doing with shafts and gears what we think takes a microprocessor. Those TDCs, German, Japanese and American, were art masterpieces as much as utilitarian machinery. Their designers were brilliant as any computer engineer of today.
