Saved an old calculator from the trash the other day. It was really beat, so I took it apart. It has what I call a vacuum display like this one. Are these collectable or useful to any electronics people?

Well, friends, finding some interesting free cаsinos for yourself is possible, but a little difficult. It's a task that's given to real people who have been looking for a very long time. I would generally recommend that you go to this site 777 slots https://www.slotsup.com/free-slots-online/777 and only here you'll be happy to find a pretty good opportunity to play at the most memorable cаsino. Also these cаsinos will be completely free for you is a great selection of such cаsinos.Originally Posted by BillChery23

Antique / Retro electronic parts can always be useful to some DIY enthusiasts and people who rebuilt old items. I would take a chance to list it on Ebay.
By the way, they're also getting more and more rare. I remember to see vacuum tubes frequently when I was younger (not that I am that old!), but it is a long time since I stumble upon one. Also, I still see CRT TV and monitors curbside on a regular basis, but I think that I saw only one (maybe two) wooden case television (probably with vacuum tubes) in the last 5 years and I can't recall the last vacuum radio I saw anywhere. Excluding museums, it would be 25+ years.
NEW TO SCRAPPING? READ THIS: Build up your horde of magnetic and non-magnetic metals in two piles until you have a better understanding of the business. Magnetic material has low value and is mostly always steel / shred / short iron. Read old threads about non-magnetic metals and ewaste (and how to sort them), but don't forget that they generally have absolutely no tolerance for contamination (screw / iron / foreign material).
