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!

Not really calculators but interesting nonetheless:

What about the HP 3478A multimeter then?

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

By 14/16, I mean the number of segments per digit. 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.

I'm more interested in handheld programmable calculators, but the question is open to other devices.

TI-62

Thanks! 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.

RE: Calculators with 14 or 16-segment displays?
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.

Hello,
Be careful, the TI-62 is legendary slow as molasses...
like you must pause a bit between keystrokes when entering numerical values.
But the machine is gorgeous, pleasing to use, powerful... albeit very slow.

It may be possible to speed it up a little bit like the TI-66.

The Multitech MicroProfessor MPF 1 Plus is using a VFD display with 20 16-segment characters :
