6 AND logic gates
12 logic lamps (preferably on)
1 teleporter
~250 wire
7 switches
6 lights
4 kinds of wire

Step 1:
Place the logic gates 1 block apart, with 2 logic lamps above each one. Put blocks down above the lamps to make a platform. Place switches just above each logic gate on the top platform, and place a light above the switches. Above the lights, to either the right or left, place down a teleporter. Then place a switch next to the teleporter.
Step 2:
Wire each switch to their respective top logic lamps, and to their lights. Connect the teleporter main switch to the bottom logic lamps with a different color. (The color you connect to the bottom lamps cannot be used for the 6 locations, unless you are adding a 7th, which is possible with proper placement.)
Step 3:
Use the remaining 3 colors to attach the logic gates to the teleporter, using each of the 3 for each end of the teleporter. Attach each color to 2 logic gates on opposite sides. Make sure wires of similar color do not come into contact.

Now all that's left is to apply locations to the switches. Simply take a color corresponding to a gate and make a wire going off of the gate wires to another teleporter. You should be able to do this without issue as long as the wires don't overlap. Only one light can be on at a time (or off if you didn't invert your lights).

Congratulations! Now you can impress all your friends with your complex-looking teleporter system. I hope this guide was helpful. Thank you for reading.

It has come to my attention that some people assume that this device is supposed to work in both directions, and automatically reset. In order to prevent further confusion, I would like to explain the details of its functionality.

Only works in one direction from the central teleport, in order to teleport back, you need to use a magic mirror. (I intended this device to be used as transportation, preferably placed within or near your base. Apperently some people don't think the same way)

The lever near the teleporter is the switch used to activate the teleporter. The lined-up switches are for selection ONLY. In addition, when you want to select a different location, you must deactivate the previously activated switch and activate a new one for a new location.

While I had hoped no assumptions would be made as to the degree of the functionality of this system, it has been brought to my attention that some people assume the system has more automation involved than was actually present.

Thank you for reading.
