Handheld and Portable Computer Club
HPCC is a voluntary, independent body run by and for users of handheld and portable computers and calculators. The club has been helping members for more than 30 years to get the most from their Hewlett Packard equipment and to further the exchange of information and ideas.
While most members' main interest is in the HP range of models, the club is happy to discuss other models too, at meetings, through the club journal - Datafile, and on these web pages. HPCC is not supported by Hewlett Packard or any other commercial organisation; its activities are funded and undertaken by its members.
