Recently, PoW ASIC mining hardware firm StrongU contacted HCASH with information stating that they had updated the firmware of their STU-U1+ and STU-U1 DCR miners to enable the mining of HC.
This means that any user who has a StrongU STU-U1+/STU-U1 miner can now (after they update their firmware), mine HC. Users wanting to update their firmware can do so here: STU-U1+, and STU-U1
Those interested in StrongU miners can find the specs of the machines below:
