Attached is a personal story of a guy who worked at the TCA in San Antonio, TX in 1983-1984. No photos from that time but interesting stories how the Model 4 was produced.

Personal Experiences at Tandy Computer Assembly.pdf
A very interesting source is Tandy's internal corporate newsletter, "Intercom". It was never public, but now that Tandy is only history, it's appropriate that the issues are now archived at the "Portal to Texas History":
It's utterly fascinating to read, back from the times when "Yes, we have factories!" (June 1977). Many behind-the-scenes stories, even of the photo shoots for the famous catalog. The late 70's computer years are on page 5 and on.
Monthly newsletter published in March 1978 for employees of the Tandy Corporation Radio Shack Division containing work-related information, updates about employees, and other news.

And the full-color cover of the April 1978 issue has a shot of a few (stacked!) on a workbench:
Monthly newsletter published in April 1978 for employees of the Tandy Corporation Radio Shack Division containing work-related information, updates about employees, and other news.
Monthly newsletter published in April 1981 for employees of the Tandy Corporation Radio Shack Division containing work-related information, updates about employees, and other news.
In that April 1981 cover, it looks like they are all working one handed - what you don't see is in their other hand, they are holding a tray of components. (there is another photo inside that shows that)
Lots of neat stuff in there. Those are really great, thank you!!
