I come across items fairly often and am "reasonable" for sure. Let me know how to reach out. I might be able to help you out.

@@ewasterecovery Awesome, thank you sir 👍

o.. you 'r not going to ..oh..oh..ok.. woosh..

btw: i got some alike.. but not that Wow.. so..

@@herauthon I do NOT refine computers boards or chips 99% of the time it is only useless Telecom Stuff.

One of my best purchases for sure.

Thank you!

All places vary. I usually pay a good amount from the places I go so I can put as much as possible back into good homes/hands. There is not set price to be honest.

LMAO

Hughes developed them I believe.

@@ewasterecovery That was the company he worked for. Those are some beautiful boards

@@The-KP Thank you! and tell him the same, lol. I am sure it took many people and countless hours for these things. Incredible...

I hope you dispose of them correctly. Hughes radar is usually military applications.

This link might help explain better than me :) - www.allicdata.com/news/ic-chips/stacking-technology-may-double-the-transistor-density-of-future-ic.html

@@ewasterecovery I don't believe it was that, but AI's answer is modertately satisfactory: Common Address and Data Lines: Since the address and data lines of the memory chips needed to be shared, these were connected together. This meant that both chips would respond to the same address and data signals. Separate Chip Enable Lines: Each memory chip had a separate chip enable (CE) or chip select (CS) line. This allowed the system to enable one chip at a time. By controlling these lines, the system could select which of the two stacked chips to access.

Thank you and ... WOW - Nice channel and videos/content and collection! 14 years running! Incredible! I cannot imagine what you have and have come across.

I did not dissemble this, I bought this from someone. I am working on figuring out where they came from. I think some came from a System 370, 4361 or 4381 or 3081 lol. I am going to do more research on Bitsavers to get more information eventually. But I am glad I saved them from where they likely would have went otherwise...

@@ewasterecovery Thank you :)

Different vendors and recyclers and also on fleabay sometimes too.

LMAO <3

Thank you for following. - I literally bought it so it would not be destroyed and paid a pretty decent amount for it. I am a collector, not only a scrapper. I only scrap items that cannot be used anymore... mostly telecom stuff. Anything I have that is already destroyed I saved from going into acids, trust me :).

@@ewasterecovery I completely understand that. I've probably spent more on obsolete tech than I should have, for the same reason.

Thank you!!! I wish I was able to get to the computers/machines before the boards in most cases, lol :(

@@ewasterecovery oh yeah I agree with you and I can understand that some people break the stuff down for gold and other precious metals but some of that stuff is so rare that at least to me it's worth a lot more than the scrap value. Nowadays all components really look the same with no personality by the engineers that design them it's a hunk of plastic silicon metal and that's it unlike the stuff of the past. If I sound crazy it's because I am due to working in the computer field since I was 15 years old and I'm in my late 40s now lol.
