This is a trip down memory lane. Someone has taken the time to preserve and document Radio Shack, its founding, history, and all of the catalogs printed from 1939 to 2005. The website archive is Radio Shack Catalogs.
I remember reading these very catalogs cover to cover when they came out in the mid-1970s. At that time, this stuff looked expensive, and in relative dollar terms compared to today, it was. We had one of these computers in our “Math Lab” in 9th grade:
In fact, when I found one of these computers stashed away in the corner of a transmitter site, I had a flashback of Mr. B scowling as yet another student made a mistake plotting x/y coordinates on the backboard.
Ahhh, memories. Enjoy!
