Let ko be the real connective K-theory spectrum. We compute koBG and
koBG for groups G whose Sylow 2-subgroup is quaternion of order 8. Us
ing this we compute the coefficients t(ko)(G) of the G fixed points o
f the Tate spectrum t(ko) for G = Sl(2)(3) and G = Q(8). The results p
rovide a counterexample to the optimistic conjecture of Greenlees and
May [9, Conj. 13.4], by showing, in particular, that t(ko)G is not a w
edge of Eilenberg-Mac Lane spectra, as occurs for groups of prime orde
