About the HPCC Journal

We have received the June-August number of Datafile, the HPCC journal. Edited by Bruce Horrocks, it is a journal made for us. I have mentioned it on previous blogs, but it is filled with interesting information for those in our hobby.

HPCC stands for Handheld and Portable Computer Club. One would have said that the initial two letters had another meaning, since all units being discussed are from Hewlett Packard.

The journal is a little booklet, A5-sized (for our american readers, the A-series of paper sizes is the standard in Europe), with 32 pages, devoid of any publicity and full of calculator related information.

There are news about calculators, hints and tips for calculator DIY (there has been a series on repairing the 9800 series of calculators,with detailed instructions and explanations about the inner workings of these machines, articles about programming in both RPN and RPL, a for sale and wanted section (that was empty in this last issue, since it is a very recent addition to the journal), and the story of an HP calculator in each issue, written by none other than Wlodek Mier-Jedrzejowicz.

In past issues, there have been articles on other scientific areas likely to be of interest to calculator users like science history, astronomy, etc. It is amazing, by the way, the number of common interest we do have part of calculators. I have met some of my customers, and we never fail to have another hobby in common - and not a normal one!

The club is celebrating its 30th anniversary, and will have its annual meeting on the 27th and 28th of October in the Imperial College in London. As it is stated in the journal, "no need to register, no charge for attendance, not even for the pie!"

I hope they do not mind if I copy the agenda!
