Only with general info from various reading...the TDC was a pretty amazing thing at the time, a compact computer! There was only ONE on any boat, any navy. They were a Big Deal. The USN had one that could update all info automatically. The Kriegsmarine's was a bit limited. They could input a problem and get a firing solution, but when things changed they had to re-input new info.
Periscopes were a Big Deal, too, but more of a Medium Deal - hi-tech optics and construction, but nowhere near as tricky and complex as a mechanical computer. The USN TDCs were big, about the size of a small fridge (not bar fridge, just a bit smaller than a double door). We're talking big stuff. VERY impressive though, from what I've read there were no major problems with them (as opposed to US radar and anyone's hydraulics at critical times).
