Two similar keypads from '80s era calculators.

I'm thinking peripheral? Would like Telco though, but think too much empty board to IC ratio?

Top one is peripheral, bottom one, keep it alone in the shipment it may get upgraded.

So, the bottom keypad in the bottom picture might get a bump due to the one extra IC and the three Tantalum capacitors?!?!

Nice!

Still trying to get a handle on when a board that appears to be relatively empty, yet could fetch a higher grade. Because.....!

Thanks for answering my “lost” posts!!!

The extra IC is a Z84C. A full, lite instruction, CPU. Is it enough to jump somewhere? I don’t know.
It it’s worth keeping it off a pile and calling attention.
