Some python tests scripts for communicating with the Bitmain BM1387 bitcoin mining ASIC.

The BM1387 is most famously used in the Antminer S9. AS far as I know there is no datasheet available for the BM1387, so this is all reverse engineering.

• The Gekkoscience Newpac is a USB stick miner that has 2 BM1387 chips. The wareck modified cgminer that supports the newpac has some hints about how to communicate with the BM1387.

• Braiins has released an open source OS for the Antminer S9 that also has some hints on communicating with chains of BM1387s via the Antminer's FPGA
