Batch two of the Z9 may not be a good purchase (I purchased 1 batch 1 and 1 batch 2).

I plan to try and mine the equihash multiport on MPH. https://miningpoolhub.com/?page=gettingstarted

It takes a bit to understand how MPH is working so you may want to mine a pool where you mine one coin directly.  Also, it sounds like right now not every equihash pool is working with this miner, although I expect that to change by the time batch two gets sent out.
