Only know that because I've got some JAN6418's

I was indeed thinking of those green VF displays on a few radios and a lot more video recorders.
They also did British hearing aid valves that were also sort of square.

While looking them out I found an open circuit resistor and discovered that the label on it has also gone open circuit
