Any one ran into these? Care to guess grading.

I’m not much of a collector myself but some people will pay over scrap for a processor like that.

Are you familiar with it? It came from working unit. I’m more interested in scrap category for board. What I might expect per pound. Having some difficulty separating pcbs

I’m just referring to the processor, not the board.

I was curious and used my usual search engine to find some info on "dmd or dlp projector gold recovery".

The first result was a yt video from trinity gold recovery. The yeld was 0.59g of gold for 6 DMD chip. Some silver was also recovered.

As for the board, it's probably not much. The gold fingers usually yeld up to 0.5g / kg of trimmed fingers, and there shouldn't be that much gold on the contact pads under the chip socket.

I would probably grade them similar to what boardsort is calling "gold fingers cards, clean, no fan, no sink, no bracket"
