Regarding other brands, the National NS-7100 is legendary as well. You can find references to that in this forum's search and the Web. I was amazed at the one I got to open up in my apartment...

That is amazing! I suspect only a handful of people were able to hold one of these prototypes in real life, let alone open it.

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.

Very interesting. Thank you.

The HP 67 was cheaper than the 65.
