Display + Keypad + 999 output

I needed a teleport system for my theme park :) this is my solution.
You have 3 keyboards and can use them to control 999 command blocks (redstone lamps).
You enter a 3-digit number and the signal finds the respective command block (redstone block).

There are definitely better and nicer solutions. Especially the redstone from the display.

I'm not good at redstone.

Here are 2 solutions: one with redstone and one where the display is created with command blocks.

Note that you have to change the coordinates for the command blocks.



Maybe someone can use this...
