Abstract: This paper describes how to compute equations of plane models of minimal Du Val double planes of general type with $ p_g=q=1$ and $ K^2=2,\ldots,8.$ A double plane with $ K^2=8$ having bicanonical map not composed with the associated involution is also constructed. The computations are done using the algebra system Magma.
