Happy Hunting!

Thank you but still nothing seems to be related in particular to the Mark 4 TDC. Its description does not seem to be easily findable on the web for some reason even though there is a lot on Mark 3.
Also I thought I made it clear that I came up with that question after already reading both the Submarine Torpedo Fire Control Manual and the Torpedo Computer Manual for the Mark 3. In fact it was reading these two that made me wonder what the difference between the Mark 3 and Mark 4 is.
