We present a new set of zero metallicity models in the range 13-80 M{sub Sun} together to the associated explosive nucleosynthesis. These models are fully homogeneous with the solar metallicity set we published in Limongi and Chieffi and will be freely available at the Online Repository for the FRANEC Evolutionary Output Web site. A comparison between these yields and an average star that represents the average behavior of most of the very metal-poor stars in the range -5.0 < [Fe/H] < -2.5 confirms previous findings that only a fraction of the elemental [X/Fe] may be fitted by the ejecta of standard core collapse supernovae.
