That's a relatively modern repro. The originals would have been a black with red numerals.
I only remember green numerals from ancient computer screens, not calculators. I don't think I have ever seen a calculator with green numerals.Or green numerals. VFD's predated the seven segment LED.
Or blue. I was once lent a calculator with 1/2 inch fluorescent display. I thought that was very pretty but I had to give it back.Or green numerals. VFD's predated the seven segment LED.
VFD calculators owned by my parents in the early '70's:I don't think I have ever seen a calculator with green numerals.
