  A modified form of quantum mechanics which includes a new mechanism for
wavefunction collapse is proposed. The collapse provides a solution to the
quantum measurement problem. This modified quantum mechanics is shown to arise
naturally from a fully discrete physics, where all physical quantities are
discrete rather than continuous. We compare the theory to the spontaneous
collapse theories of Ghirardi, Rimini, Weber and Pearle, and argue that the new
theory lends itself well to a realist interpretation of the wavefunction.
