Some Other Fine Acronyms Cards
SOFACards were originally published as flash cards on two-sided business cards. They provide bite-size bullets of information for those desiring less than a full book's worth regarding information technology topics.
One side of each card has an industry word or acronym, with an explanation on the flip side. Only the flip side is presented in this web page slide show format.

R83, µData, and PI
These cards use the terms R83, µData, and PI to identify three not-entirely-distinct streams of development of the MultiValue platform. The MultiValue Family Tree diagram, available as a free pdf from store.tincat-group.com, provides a corresponding visual. These terms are used at times in the cards as shorthand identifiers for the three interwoven but separate branches of MultiValue.
In the late 70' s, the Pr1me Information (PI) stream started, emulating functionality roughly equivalent to Microdata's Reality 3.x product (µData), which was roughly equivalent to Pick® R77. After that (e.g. R83), the streams diverged. Pick historians indicate that R80 is the software version that was marketed as R83, but the marketing term serves our purposes in these cards none-the-less.
Terms related to MV data and commands are identified with the two primary flavors -- R83 and PI -- with µData typically aligned with the R83 camp.
