PPC Journal

{{Short description|Technology magazine (1974–1987)}} {{italic title}} {{Use dmy dates|date=April 2020}} '''''PPC Journal''''' was an early hobbyist computer magazine, originally targeted at users of HP's first programmable calculator, the HP-65. It originated as ''65 Notes'' and the first issue was published in 1974.<ref name="pah"/> It later changed names in 1978 to ''PPC Journal'' and in 1980 to ''PPC Calculator Journal''.<ref name="pah">{{cite web|title=PPC Archive Version 2.37|url=http://www.pahhc.org/ppccdrom.htm|work=PAHHC|accessdate=22 April 2020|date=1 April 2020|archive-date=17 February 2020|archive-url=https://web.archive.org/web/20200217015616/http://www.pahhc.org/ppccdrom.htm|url-status=live}}</ref> With Volume 12 published in 1984 the magazine was renamed ''PPC Journal''.<ref name="pah"/> The magazine ended publication in July 1987 (Volume 14).<ref name="pah"/>

The founder of the ''PPC'' (Personal Programming Center) and editor of the journal was Richard J. Nelson.<ref name="HP Solve"/> This hobbyist group worked around the journal and was known because Nelson discovered hidden instructions on the HP-65 calculator. Later the club and the journal got maximum notoriety when several club members discovered the "synthetic instructions" of the HP-41C.

==Competition== A similar journal since 1976 was ''52-Notes'' for the Texas Instruments SR-52 user community.<ref name="Vanderburgh_52-Notes"/> It was edited by Richard C. Vanderburgh.<ref name="Vanderburgh_52-Notes"/> Both journals deliberately established a mode of "friendly competition", often exchanging information and comparing solutions among user groups.<ref name="Vanderburgh_52-Notes"/> This journal was later renamed into ''TI PPC Notes'' and edited by Maurice E. T. Swinnen (from January 1980 to December 1982) and Palmer O. Hanson, Jr. (from January 1983).
