insane boards
So much change in nowadays boards
Just found you channel, awesome stuff ! I am trying to level up my own collection, it is sad to know that the gold refiners are hunting hard also to get this quality of boards, just to finally destroy them.
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.
Where do you find this rare material?
Different vendors and recyclers and also on fleabay sometimes too.
Hello, what is the model of this computer you disassembled?
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 :)

How do double stacked chip work?! we are not talking about amplifiers amplifying a singal twice. how are the 2 chips adressed? do each chip have an "ID"? like a modbus address of some sort so that only one chip will put data onto the bus at a time? now I think about it, i don't know how modern memory chips work either.
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.
The numbers after IBM - such as IBM 22 - aren't significant. The IBM part number is the 7-digit number above that on the metal can. The chips made by other manufacturers also have 7-digit IBM part numbers.
