Digital Computer: Gemini

Virginia Standard PS11 Investigate and Conductors,Semiconductors, and Insulators

In 8th grade physical science, we explore a simple blinker circuit, trying to draw a schematic of what is observed on the circuit board, trying to identify parts of the circuit. A few interested students can build one after school (we have limited access to the soldering irons and kits, so not everyone builds one).

I would use the Gemini computer photo to provide a historical perspective, and would use it before the blinker circuit exploration (link below). I would use the LOC Primary Source Analysis Tool https://learninglab.si.edu/resources/view/82176

This computer was transferred from NASA to the Smithsonian in 1973. Info from the SI Learning Lab explains:

"This is an on-board guidance computer used in the Gemini program. In contrast to Mercury capsules, which had no on-board computing capability, Gemini spacecraft required an on-board computer to assist in rendezvous operations and in maneuvers to change its orbit. Both were necessary steps to lunar expeditions undertaken with Project Apollo.

The computer used discrete, solid state components and magnetic core memory. It was manufactured by IBM. This specimen is probably an unflown test article."
