I have computed the (mod 2) Adams E2 terms for the stable homotopy groups of some Madsen-Tillmann spectra. Recall that $\mathbf{MTO}(2)$ and $\mathbf{MTSO}(2)$ are respectively the homotopy-types of the non-orientable and oriented stable mapping class groups, after plus-construction. This uses Robert Bruner's program for calculating Ext groups over the Steenrod algebra. I wrote a MAGMA program to give the description in terms of generators (up to a given degree) of these modules over the Steenrod alegebra, in a format admissible for the program mentioned above. There is also a chart for the beginning of $\mathbf{MTSO}(2)$ with some differentials filled in here, which are those which can be deduced from John Rognes' "Two-primary algebraic K-theory of pointed spaces", Topology 41 ( PDF).
