Astrological Computing

Astrological Computing

Astrological Computing refers to the intersection of computer programming, software engineering, and mathematical algorithms with horoscopic calculation and analysis. Emerging alongside the microcomputer revolution, this field encompasses the development of source code for natal charts, planetary hour calculations, custom glyph rendering, and hardware-based astrological tools. Within library and archival classification systems, this category organizes technical periodicals, historical software source code, algorithmic manuals, and documentation detailing the technological evolution of automated celestial calculation.

Matrix Magazine Issue VII 1980

Computer Astrology, Astrological Software, and Uranian Astrology. This archival document is a complete issue of Matrix Magazine (Issue VII, 1980), edited by Michael and Margaret Erlewine. The magazine focuses on technical, mathematical, and computer-assisted astrology during the early microcomputer era. Key features include James Neely’s derivation of orbital elements for Transneptunian planets (Cupido, Hades, Zeus, Kronos, Apollon, Admetos, Vulkanus, and Poseidon); Michael Erlewine’s complete BASIC natal horoscope program code; Mark Pottenger’s algorithms and source code for Astro-Geography/AstroCartoGraphy and Fixed Star comparisons; Dwight William Johnson’s mathematical method for computing planetary hours; and an introduction to the hand-held ASTEK I astrological computer. The issue also includes the presentation of the 1980 Johndro Award to Neil F. Michelsen, discussions on micrographics for document storage, dot-matrix custom astrological glyph design, and the complete schedule for the first Astrological Conference on Techniques (A.C.T.).
