How did it fail? Can you be more specific? Is there any error message?
And no, there are no minimum requirements. I have heard people mining on old machines. It would be interesting to find out what oldest machine found a block.
Old machine is a PC right? not a rig miner?
I got Intel core i3 with 4gb ram, intel hd 3000.Os old win 7
So I edit new wallet bat file.run it but the cmd screen appear only 1 sec. and there is no new file. this kind of stuff is new for me.sorry if this question is bother you.
One of my machine is i3 and it is still finding block or two every day.
It has been a while since I created a wallet file, but you should first run
new-wallet.bat and then it should generate two new files, one that ends with
.wallet and one with
.wallet.address. Only then you edit
wallet.bat file. There is a
win-start-readme.txt instruction file that explains it in more detail.
