Keep Talking and Nobody Explodes Mod Not Symbolic Coordinates

On the Subject of Rewording Not Symbolic Coordinates

These symbols are probably a reference, so if it still does not make sense to you, that is still your fault.

  • The module will display three symbols and six LEDs, three of which are coloured.
  • The colours of the three LEDs above the submit button correspond to pairs of truth values, where F is false and T is true. To find which colour corresponds to which pair, start with the table below:
    1. Shift each colour one space to the right for each battery on the bomb, wrapping around to the other side if necessary. (1 bat. GYAP→PGYA)
    2. Then, if a TRN indicator is present, reverse the order of the shifted colours. (GYAP→PAYG)

  • Each symbol represents the numeric value corresponding to its position in the display and the truth values corresponding to the other two, in order. (E.G. The 1st displayed symbol represents 1st numeric value, and 2nd and 3rd truth values in the table.)
  • Of the three vertical LEDs on the right side of the module:
    • If the top LED is lit, negate the first truth value of all three pairs.
    • If the middle LED is lit, negate the second truth value of all three pairs.
  • The pairs of truth values indicated by the colours of the LEDs are the desired outputs of two sets of logical operators whose inputs are the pairs of truth values received from the symbols.
    Within each set of operators:
    • Using the first and second displayed symbols, take the first truth values and apply left set Operator 1. Then take the second truth values of the same symbols and apply left set Operator 2. The result of Operators 1 and 2 from the left set outputs the respective truth values of the colour of the left LED.
    • Using the second and third displayed symbols, take the first truth values and apply right set Operator 2. Then take the second truth values of the same symbols and apply right set Operator 3. The result of Operators 2 and 3 from the right set outputs the respective truth values of the colour of the right LED.
    • Using Operator 3 of the left set and operator 1 of the right set, examine the first and second truth values from the first and third displayed symbols, and go over these conditions:
      • If a CLR indicator is present, operator 3 is applied to the first truth values of the first and third symbols and operator 1 is applied to the second truth values.
        Otherwise, operator 3 is applied to the second truth values of the first and third symbols and operator 1 is applied to the first truth values.
      • If the bottom LED is lit, operator 3 outputs the first truth value in the pair and operator 1 outputs the second.
        Otherwise, operator 1 outputs the first truth value in the pair and operator 3 outputs the second.
      This pair of truth values outputs the colour of the middle LED.
  • Scroll through the two displays to find and submit the pair of operator sets that output the three colours. There will only be 1 of each set on the left and right that matches.

Symbol Values

The 3 numeric values, the sum of the pairs of numeric values, and the sum of the 3 numeric values must be kept within 0 - 99 inclusive by taking those numbers outside of the range, modulo 100. For determining truth values, when “value” is used, it references the numeric values of the symbols displayed.

Appendix: Other Notes

Any number is NOT divisible by 0, including 0.

Prime numbers before 100: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

1 is not considered to be prime.

Vowels mentioned in the manual refer to the letters “AEIOU,” while consonants do not refer to those letters.

The digital root of a number is obtained by taking the sum of the digits of the original, repeating this process until you have 1 digit remaining. That digit is the digital root of the original number.

A modulo B, or A mod B, is obtained by finding the remainder when dividing A by B, or by repeatedly subtracting B from A until A is less than B.
