Calculators with 14 or 16-segment displays?
I'm sure I'm missing some calculators but I can only think of the HP-41C and the TI-66.

RE: Calculators with 14 or 16-segment displays?
Hello!
The only two others that came to my mind quickly are the "MBO Pocket Computer 2000" and the "Nixdorf LK-3000" (also known as "Lexicon LK-3000"). They are from the late 1970ies and the MBO has a VFD display and the Nixdorf uses LEDs. They are a bit larger than an ordinary pocket calculator and accept cartridges that can turn them into a calculator, language translator and maybe other things as well. Unfortunately I only have a couple of MBO devices and several language modules but was unable to find a working Nixdorf for an acceptable price. Regards Max NB: Personally (no offence intended) I think that 14 and 16 segment displays are the ugliest form of man-machine-interface ever invented and one reasons why I never liked the HP-41. |

Funny, that's one of the reasons why I love it! Greetings, Massimo -+×÷ ↔ left is right and right is wrong |

Not really calculators but interesting nonetheless:

Nixie tube machines often have 14 or even 16 digits. (Maybe a kind of race who could do more?)
Does that count as 14 or 16 segment display? Or was the original question exposed to pocket calculator? - my guess Andi |

Earlier calculators had 7-segment digits which can represent all the digits 0-9 as well as the minus sign. With 14 segments, uppercase letters A-Z can be represented as well. https://en.wikipedia.org/wiki/Seven-segment_display https://en.wikipedia.org/wiki/Fourteen-segment_display I'm more interested in handheld programmable calculators, but the question is open to other devices. |

I may grab one since it seems to be a natural evolution of the TI-57 (unlike the weaker TI-57 LCD): a little bit more powerful and with an alphanumeric display for LRN mode. |

The TI Financial Investment Analyst (Datamath) uses some 14-segment "digits". There is a group of three on each of the top five rows of the display, acting as a three-character label for each row; the 12 digits of the bottom row are also 14-character digits, used for both numbers and messages.
