Probably worth more as a "Nerd Collectible".
Yeah probably. But too late I'm thinking. It's so pretty I don't even want to or even know how to process such beauty. Any suggestions? 8)

That calculator you have screenshotted is completely different. What model is that cause I tried finding 74' that looked like it. They were anywhere from $150-599.+
However the ones I saw had an orange and blue button where as the one you show I only see the orange. Which could be a good thing cause it could be an earlier version.
It's hard not to get excited when you see gold we all get that. But why take something you could potentially get $100+ and just buy gold instead of tearing it apart and only getting 1/4th of that.

Yes as I said I understand. And I'd love to make more. But I have no idea where to sell such things. But my eyes are open and look into in the future. And your right now that I look at it that isn't the same one. Oops. I think this one is a hp45 if I remember.

It’s always easy for guys to bust your chops about scrapping and processing things but in all honesty is your stuff. Of course it makes sense to be certain you don’t have a 500.00 collectible before you rip it apart but at the end of the day if you enjoy what your doing with it then who cares, it’s yours. Hell lots of people would just toss it in the trash never knowing what’s inside.
Scrap what you want and don’t worry about the people who gripe about what you coulda got. Heck I have piles of vintage testing equipment that’s about to be scrapped for 100th of what it’s probably worth because I can’t find a buyer and I’m sick of looking at it. It’ll be a pile of copper, silver and gold contacts soon.
Scrap on and make no apologies for enjoy your stuff the way you choose to enjoy it.
Thanks

So if you were to process it what process would you use would take off all the components
To get the ic chips and stuff off? I used heated soldering iron on back while prying off the components off the front with hand tools. Haven't processed any yet though.

I have removed chips from many circuit boards using a heat gun, which melts all the solder at one time from the part you want to remove. Much easier than trying to desolder a multi-pin chip with a soldering iron.
As for the value of HP Calulators, the HP-35, HP-45 and HP-55 are very collectible and can be sold easily on Ebay.
If you come across any 1970s vintage ceramic Intel CPU chips, on or off a circuit board, let me know and I'll probably be able to buy them from you at a much higher price than the value of the gold on the chip. Price depends on the chip part number on the Gold cap.
