We extend the model of string as a polymer of string bits to the case
of superstring. We mainly concentrate on type II-B superstring, with s
ome discussion of the obstacles presented by not II-B superstring, tog
ether with possible strategies for surmounting them. As with previous
work on bosonic string we work within the light-cone gauge. The bit mo
del possesses a good deal less symmetry than the continuous string the
ory. For one thing, the bit model is formulated as a Galilei-invariant
theory in [(D - 2)+ 1]-dimensional space-time. This means that Poinca
re invariance is reduced to the Galilei subgroup in D - 2 space dimens
ions. Naturally the supersymmetry present in the bit model is likewise
dramatically reduced. Continuous string can rise in the bit models wi
th the formation of infinitely long polymers of string bits. Under the
right circumstances (at the critical dimension) these polymers can be
have as string moving in D-dimensional space-time enjoying the full N
= 2 Poincare supersymmetric dynamics of type II-B superstring.
