External Clubs & Collections

HPCC is a voluntary, independent body run by and for its members. It was originally set up as a self-help group for users who were interested in getting more out of their Hewlett Packard Handheld and Portable Computers, hence the Club’s initials. The club is still devoted to helping members get the most from their equipment (both HP and other makes) and to further the exchange of information and ideas on various technical topics of mutual interest. HPCC is not supported by Hewlett Packard or any other commercial organisation; its activities are funded and undertaken by its members.
