  For every genus g, we construct a smooth, complete, rational polarized
algebraic variety DM_g together with a normal crossing divisor D = sum D_i,
such that for every moduli space M_C(2,0) of semistable topologically trivial
vector bundles of rank 2 on an algebraic curve C of genus g there exists a
holomorphic isomorphism f: M_C(2,0) minus K_2 -> DM_g minus D, where K_2 is the
Kummer variety of the Jacobian of C, sending the polarization of DM_g to the
theta divisor of the moduli space. This isomorphism induces isomorphisms of the
spaces of conformal blocks.
