We propose some new simplifying ingredients for Feynman diagrams that seem
necessary for random lattice formulations of superstrings. In particular, half
the fermionic variables appear only in particle loops (similarly to loop
momenta), reducing the supersymmetry of the constituents of the Type IIB
superstring to N=1, as expected from their interpretation in the 1/N expansion
as super Yang-Mills.Comment: Section 5 which describes contributions of the string measure adde
