Calculator displays

[Warbucks]

Update on calculator display options:

Individual red 7 seg leds are available though mounted two per small pcb. Lot size is reasonable.

Also available 14 (+3 punctuation) seg individual red leds.

LCD displays that can display a nice "font" instead of what the 41 presented us with.
For purists, the old style is available too.

I was also shown an assembly that would let me change the display in the field with a selection of display modules. A 41 with red leds or how about a small led capacitive touch screen that will display any font any color?

On a different front, there are some new arbitrary precision algorithms for elemental
functions. I'm going to implement them for testing. I need to make sure of their provenance though.


Edit:

In the zip file are two images, the one with 9 leds if you cut the end two off, that is what he has. He also said the five led chip is available. I await his remit.

Thanks for your time and advice.
