Micropendium Magazine
Micropendium was a magazine all about the TI-99/4A that ran from 1984 to 1999.
As a whole, this periodical functions as a record of one of the longest-running conversations about the Geneve 9640 from the time period. You can find articles, correspondence between readers, and more that directly address topics relating to the Geneve ecosystem and to the Myarc company in general.
