vintageTEK has received a number of Technology Reports for our Library
The intact ones are dated from 1982 through 1985 with a front cover title TEK Information For Technologists and were Company Confidential at the time. The full issues we have are creme colored, and a number of articles were extracted from other versions that were printed on tan or light brown paper. We are not certain whether this color was earlier or later issues.

Besides Technical Articles Engineer Profiles were also included, a sample I have attached here on Charlie Rhodes.  Charlie Rhodes Technology Report Article
