Random alphanumeric character

From MegaTravellerWiki

Throw 2d6 and read one die then the other die to produce a number from 11 to 66.

11: A    21: G    31: M    41: S    51: Y    61: 1
12: B    22: H    32: N    42: T    52: Z    62: 2
13: C    23: I    33: O    43: U    53: 0    63: 3
14: D    24: J    34: P    44: V    54: 7    64: 4
15: E    25: K    35: Q    45: W    55: 8    65: 5
16: F    26: L    36: R    46: X    56: 9    66: 6

Model Numbers

• Roll 1d6+2; this is the number of symbols that appear in the model number.
• Roll 1d6; if 3+, the model number contains a hyphen.
• Roll 1d6; this is the character that the hyphen appears before, if any. If the number rolled is greater than the number of symbols in the model number, the hyphen does not appear. If the number rolled is 1, the hyphen does not appear.
• For each symbol, roll on the above table.

Example:

• Symbols = 1d6+2: 4+2=6
• Hyphen? = 1d6: 3 = Yes
• Hyphen Pos = 1d6: 5
• For each symbol:
  1. 1d6/1d6: 33 = O
  2. 1d6/1d6: 55 = 8
  3. 1d6/1d6: 32 = N
  4. 1d6/1d6: 24 = J
  5. 1d6/1d6: 14 = D
  6. 1d6/1d6: 45 = W
• Result: O8NJ-DW

Modification: Numeric Tendency

• Roll 1d6. If 3-, numbers appear first. If 4+, numbers appear last.
• Roll 1d6+2; this is the total number of symbols that appear in the model number.
• Roll 1d6/2, rounding up; this is the number of "letters" that appear in the model number.
• The difference is the number of "numbers" that appear in the model number.
• Roll 1d6; if 3+, the model number contains a hyphen.
• Roll 1d6; this is the position of the hyphen, if any, using the rules above.
• For each "letter", roll on the alphanumeric table.
• For each "number", use a d10 if you have one, or roll on the following table:

11: 1   21: 7   31: 3   41: 9   51: 5   61: Re-roll
12: 2   22: 8   32: 4   42: 0   52: 6   62: Re-roll
13: 3   23: 9   33: 5   43: 1   53: 7   63: Re-roll 
14: 4   24: 0   34: 6   44: 2   54: 8   64: Re-roll
15: 5   25: 1   35: 7   45: 3   55: 9   65: Re-roll
16: 6   26: 2   36: 8   46: 4   56: 0   66: Re-roll

• Arrange in appropriate order of "numbers" and "letters".

Example:

• Order = 1d6: 1 = Numbers First
• Symbols = 1d6+2: 5+2 = 7
• Letters = 1d6: 3 = 3 letters
• Numbers = 7-3 = 4
• Hyphen? = 1d6: 4 = Yes
• Hyphen Pos = 1d6: 5
• For each letter:
  1. 1d6/1d6: 46 = X
  2. 1d6/1d6: 11 = A
  3. 1d6/1d6: 65 = 5
• For each number:
  1. 1d6/1d6: 32 = 4
  2. 1d6/1d6: 41 = 9
  3. 1d6/1d6: 22 = 8
  4. 1d6/1d6: 64 // Reroll: 1d6/1d6: 53 = 7
• Numbers appear first.
