Apple model A1254 wireless router and network-storage hardware from the first-generation AirPort Time Capsule family, with the enclosure directly marked “Pre-PVT Config 70,” indicating a configuration before Production Validation Test (PVT). Because this is pre-PVT engineering hardware, do not assume normal retail firmware, compatibility, storage capacity, or functionality. Listing is for the unit shown. The unit feels light to me and I'm fairly certain that it doesn't contain a hard drive but I have not opened it (given the annoying process of opening these things) or tested it.Please review all photos for the exact markings and condition.
