As vintage computing "hardware" and misc. one of my favourites are the vintage pocket LED-calculators - I find the old-style led-display much more enjoyable than the equivalent monochrome LCD from their modern brothers, and also, much more practical to use in lowlight  - of course, if you don't care about the energy drainage
Here is o picture of two calculators on my collection:
One is a Casio FX-120 that many people are familiar with , and the other is a Felix CE-812, a local design, produced in the 80's here in comunist Romania. - the display of the "Felix" is a bit quirky , since the "glass" covering the LED-s acts also like some sort of lense ...
I invite others to post pictures of their led-calculators

I love old calculators, as a kid I always wondered why when you held multiple keys down at once it would light random paterns on the display (probably the tiny computer just doesn't understand what's being pushed and is like 'huh?')
I'll have to see if I can find any of my old calculators.
BTW, is the one on the right actually LED, or is it VFD? (or would you know?)

I used to use my dads old Sinclair LED calculator, I remember typing in the 'programs' to get it to play simple games. I had a ancient led texas instruments calculator a long time ago also, no idea what happened to that though...

I think that they are both VFD - was my mistake
Can one of the mods change the title to :
"LED and VFD calculators" ?
Thanks

Here's my trusty old TI-1025 calc. In constant use for over 30 years (they sure don't make them like they used to...).

I just got my first retro calculator today. A Commodore 786D. :-)
I couldn't test it when I bought it but when I got home it worked fine.
The only problem is the top line of all numbers doesn't work so I can't
see the difference between a 1 and a 7, anyone know how I could solve this?
It was only 1 euro, so no big loss if I don't get it fixed. ;o)
