Thanks to the many MoD readers who have entered their RHOTUKA codes into the RHOTUKA Code Reposity , it should now be obvious to most everyone that the RHOTUKA codes have more in common with the KANOKA Card than with the KANOKA disks . The KANOKA cards had pseudo-random, unique eight-character codes printed upon them whereas the KANOKA disks have a limited number of three-digit codes. The RHOTUKA codes are only six characters, but they do appear to be unique. So much for collecting them all! Forum Link
