  In this paper, we study the moduli space of $1|2$-dimensional complex
associative algebras, which is also the moduli space of codifferentials on the
tensor coalgebra of a $2|1$-dimensional complex space. We construct the moduli
space by considering extensions of lower dimensional algebras. We also
construct miniversal deformations of these algebras. This gives a complete
description of how the moduli space is glued together via jump deformations.
