Results are presented from Fermilab E-400 on the production of charmed baryons and mesons at a mean energy of 640 GeV. We show evidence for the charm-strange baryon, Ξc+, and present our measurements of its mass, width, lifetime, cross section and relative branching fractions, and the A, ξf, pt, and particle/antiparticle dependence of the state. We show evidence for both the Σc++ and Σc0, and present measurements of three mass differences, Σc++ - Σc0, Σc0 - Λc+, and Σc++ - Λc+. Measurements of the A dependence and particle/antiparticle ratios for Σc production are also presented. We show preliminary results on the ratio of two decay modes of the D0, D0 → K+K- and D0 → K0K0. The latter mode has not been previously observed.
