We study the symplectic cohomology of affine algebraic surfaces that admit a
compactification by a normal crossings anticanonical divisor. Using a toroidal
structure near the compactification divisor, we describe the complex computing
symplectic cohomology, and compute enough differentials to identify a basis for the
degree zero part of the symplectic cohomology. This basis is indexed by
integral points in a certain integral affine manifold, providing a relationship to
the theta functions of Gross, Hacking and Keel. Included is a discussion of
wrapped Floer cohomology of Lagrangian submanifolds and a description of
the product structure in a special case. We also show that, after enhancing
the coefficient ring, the degree zero symplectic cohomology defines a family
degenerating to a singular surface obtained by gluing together several affine
planes.
