Hello All,
I have a circuit board I'm trying to identify. This exact model of circuit board was given to me by my grandparents who owned a business equipment store with a repair shop. I was always fascinated by this board as a child.
Sadly, over years this circuit board was lost, but I stumbled on the same exact model of board on eBay recently and purchased it. Now I'm trying to determine it's origin. I'm thinking late 60 to early 70 desktop calculator. Presently I'm thinking it's from a Marchant Cogito. Possibly model 1016PR as this mentions core memory in its literature. The board is marked SCM 10095. SCM could mean Smith Corona Marchant.

If you know it please let me know. If you can share any documentation that would be wonderful!
Thanks for looking,
Nate
