HP's first programmable calculator, the
HP-65. It originated as ''65 Notes'' and the first issue was published in 1974.
It later changed names in 1978 to ''PPC Journal'' and in 1980 to ''PPC Calculator Journal''.
With Volume 12 published in 1984 the magazine was renamed ''PPC Journal''.
The magazine ended publication in July 1987 (Volume 14).
The founder of the ''PPC'' (Personal Programming Center) and editor of the journal was Richard J. Nelson.
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.
It was edited by Richard C. Vanderburgh.
Both journals deliberately established a mode of "friendly competition", often exchanging information and comparing solutions among user groups.
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).
