I was just thinking about that.  You could use a bitcoin cash address and mine in a pool.  But the funny thing is when you look at the difficulty to rewards, I'd rather stay on bitcoin.  The rewards just don't match up to being worthwhile.  THe longer I mine bitcoin the better the odds of hitting a block over time, or never.  But I'll take that chance.  The difficulty in BCH is very high and rewards are low. 

If you started a fresh Apollo II with blank node memory, you could redirect the bitcoind to a BCH node and download the BCH blockchain, then solo mine when it was complete.  That's what I was thinking about.  Would need a new memory card so you don't confuse it with Bitcoin.  Maybe even a new microsd after reprogramming the bitcoind to the BCH blockchain.
