<a href="https://www.youtube.com/watch?v=aXb4z2Ex3Jc&t=384">6:24</a> The Anita calculator was solid state. It just used neon filled Nixie tubes as a display. No vacuum tubes. I had a similar calculator in my lab in 1973 at the University of Alberta. With 13 Nixie tubes for a display. I have a clock now in my bedroom that simulates Nixie Tubes in colour with 10 LEDs per digit, each of which has a small microcontroller in it.
