Preliminary specifications for the NS-7100.

Here is the NS-7100 page in the 1976 Olympic Sales Company catalog
   

Here is the full 1976 Olympic Sales Company catalog where the above NS-7100 page was taken from. It shows calculator models (and their selling prices) that were available at the time the NS-7100 was being developed.
