At the moment this miner is locked to Monero and can´t mine other RandomX coins.
I'm not aware of any other RandomX coins.
About other algos it may be marketing or an unintentional consequence. It just needs the SW to support the cluster
and it can be programmed to do what any CPU can do. It may be just a matter of new FW for the controller to turn it
into a fully programmable CPU cluster. It may even be in Bitmain's plans to sell CPU mining appliances, just speculating.
