The TI-58 introduced in July 1977 had twice the memory, software modules and a lot more functions for only about $125. This was probably the nail in the coffin for the NS-7100.

Yes. That time even had a name: "The Great Calculator Wars" There was a big shakeout of companies such as NS and Lloyd.

Ah, yes. I remember those times well. I was a bit late to the game as I spent a fair amount of 1974 trying to persuade my mom that getting a calculator would not ruin my ability to do math with a pencil and paper. I finally won out and have been obsessed with them ever since. Here is one of my favorite descriptions of the development of the pocket calculator.
