Turing Machine Bytes expander
Expander module for the Turing Machine which allows sequences from 1-16 steps in length (instead of the fixed 8 or 16 steps that the TM provides by default). Discussion at http://www.muffwiggler.com/forum/viewtopic.php?t=107533&postdays=0&postorder=asc&start=0

These merchants probably sell this module. Huh?
