The "nightly" Anita inner life: The thyratrons flow redly, flashing during calculating.
This is a part from the numeric display. The gas-filled nixie tubes (glow lamp's principe) came onto the marktet just in time.
The upper circuit board contains a ring counter. The gas-filled thyratrons are very small. This was the only way to place approx. 144 pices into a manageable case. These relay tubes have only two states like mechanical relays. Additionally there are 11 vacuum tubes (ECC 82, left side) built into the calculator.
The complete counting decade with a nixie tube is shown below.
