Great thank-you!
Sheesh, it does seem like a stupid question now that I know the answer - I don't recall learning/hearing that anywhere in my interweb travels so thanks for taking the time to respond.
So is it safe to assume that:
1. there are no limitations on the minimum size of memory needed to mine ZenCash, ZCash, or other equihash crypto?
2. any other ethash cryptos also have DAG files? Or is it an Ethereum specific thing?
3. I am a butcher or fisherman?
