STB #6 – Hand build timer from the 1970s. Picked it up at Boeing Surplus

In this video we’ll take a quick look at a hand build timer. It was built by an employee of Boeing in the mid 1970s. I picked it up at the Boeing Surplus store well over a decade ago. Alas the Boeing Surplus store has faded from history, I miss my trip to the store every weekend to dig for lost treasures. It used TTL logic and 7-segment displays with mid 1970 date codes and was wiretapped. It’s a typical hand built item from that era.
