These scans all show various aspects of the construction steps that “Mac” followed to create a point contact transistor.  The text on the left is from an August 1953 TI publication entitled “texins”. The article describes the process for building a point contact transistor.  The hand drawn sketch at the top of this page is a recent correspondence from “Mac” detailing his memories of these same assembly steps, as he remembers them, from his first TI assignment almost 50 years ago.  The small item shown above with the yellow background is approximately 1” across from tip to tip.  This is an actual set of points from “Mac”, shown as first assembled and then as folded for mounting on the header for placement on the germanium block of a point contact transistor.
