We classify supersymmetric D0-D_p bound states with a non-zero B-field by considering T-dualities of intersecting branes at angles. Especially, we find that the D0-D8 system with the B-field preserves 1/16, 1/8 and 3/16 of supercharges if the B-field satisfies the "(anti)-self-dual" condition in dimension eight. The D0-branes in this system are described by eight dimensional instantons on non-commutative R~8. We also discuss the extended ADHM construction of the eight-dimensional instantons and its deformation by the B-field. The modified ADHM equations admit a sort of the 'fuzzy sphere' (embedding of SU(2)) solution.
