I agree. I would rather see a control panel where I could click on the buttons to set the range, bearing, the target's course, and speed.
If you need an example, play a submarine simulator like Silent Hunter or Silent Hunter II. The Torpedo Data Computer. Battleships use a similar machine, even in the 1990s when the four Iowas were in fleet service. The US Navy didn't try to replace the mechanical computer because it already worked well enough and was just as reliable and battle hardened as a computer. Plus, EMP wouldn't knock it out.
