Generally referred to here as black fiber CPUs. Over the years, a few dozen threads have cropped up regarding them. The search function should be helpful to locating some of those threads. Since I do not process electronic scrap, I will be of no help otherwise.

Time for more coffee.

When I accumulate a few kilos, I either offer them here, or sell to a company such as Boardsort. Have fun.

Yes they have gold bond wires. The central section is basically the same as a normal IC chip and can be processed in the same way. The rest is tricky to process economically.
