The surfaces of the 82 remaining fragments of the Antikythera Mechanism, imaged by the HP Labs team, are available for download here as at the original HP Labs download page. 82 PTMs are listed, this number being a coincidence, since some small fragments are grouped into a single PTM, and the larger fragments are imaged on more than one PTM per fragment.
You will have to download the PTM viewer (available on the same page) to browse the data on your computer.
You can also browse online the "Interactive Relighting of the Antikythera Mechanism", which is a small portion of the total data set, provided at a reduced resolution. No PTM viewer is needed, but the Java Runtime Environment has to be installed on your computer.
Download the attached pdf files at the bottom of this page the browse the complete list of the PTMs, with the corresponding fragments and views. See also this cross reference list compiled by Herb Johnson, between the PTM numbering scheme and the standard nomenclature for the Antikythera Mechanism fragments, which is based on the work done by Mary Zafeiropoulou.
