Miners for AMD without GCN

I’m just getting started with mining and have a 980ti which I can use almost any miner for. I’ve also got two old HD 6970s laying around and wanted to try to mine with those but all the miners I’ve seen require GCN architecture which wasn’t introduced until the 7000 series of cards. Are there any zec miners that work without GCN? Thanks for any insight into this.
