MAJOR UPDATE

In May 2024 we built the first draft of the
Massimo Rinaldi  IME 84 archive with kind & gracious assistance of The Engineer Massimo Rinaldi's family!

ALSO

In 2026, new high resolution photographs were  added showing the Friden 130 / Robert A. Ragen Photo-Timeline of the Prototy0ping Process!

Robert Ragen is the legendary inventor of the Friden 130, regarded by many scholars as the first commercial transistorized desktop computer / calculator. The Robert A. Ragen Archive, presented here for the very first time, consists of vast - previously unknown & unpublished - Friden Calculator development artifacts including prototypes, color slides, audio tapes of key internal discussions, and much more. 

Additionally, a new exhibit showcases a selection of Robert Appleby Ragen's previously unpublished personal photographs and biography, also taken/sourced from the Robert A. Ragen Archive, and with kindness and consultation from the family of Robert A. Ragen. This photobiography grants an unprecedented and captivating glimpse into the enigmatic personal life of one of history's most brilliant, innovative, and influential inventors.    

**ALSO**
The 2nd earliest known public press release and earliest surviving prototype for any commercial transistorized desktop computer
was recently discovered by
The Museum of TrailingEdge Technology.
