You won't need a datasheet. Just copy or build an electrically equivalent board to mount a stack of chips on. The only think tricky about this ASIC is the secret recipe inside.

All the circuitry of miners is very, very simple.

If you get ASICs to sample, we can just replace one ASIC on a working board to test. easy, easy.

Head's up. Common Chinesium scam method:
- send working samples, aka actual ASICs pulled from S9 miner, to build trust
- continue to send pulled chips to get the pump primed
- receive money for bulk order
- send 20% real chips, 80% fakes
- Oh, so sorry for your trouble, please return failed units so we can analyze
- replace the 80% fakes with another 20/80 mix
- Oh, so sorry for your trouble, our analysis indicates you have installation method problem. We will offer you another replacement. Please return the chips that failed.
- return a 30/70 mix
Oh, so sorry. It looks like you did not fully correct you installation techniques. Perhaps we should build these boards for you here. Send us more money so we can start.

You see how this works? Many people there get very, very rich with this scam.
