DATAFILE library

[rprosperi]

Another, broader source is to get a copy of Jake Schwartz' PPC Archive collection, available here:

http://www.pahhc.org/ppccdrom.htm

This contains essentially all of:

- HPCC Datafile issues
- PPC Journal and other publications
- Publications of other Calculator clubs (CHHU, HPX, Australia and NZ clubs, etc.)
- HPCC Conference Proceedings
- HP Periodicals, such as HP Journal, Digest, Key Notes, Key Bits, etc.
- EduCALC Catalogs and other EduCALC publications
- many hundreds of HP (and related 3rd party) brochures, catalogs, papers, reviews, etc.

It's not quite free, but pretty darned close considering its scope. Basically it's a 1-stop shop for nearly all published materials for HP's rich calculator history.
