Can someone explain how this addresses can try find and get using? I have old mining hardwares with good processor and want to try

What softwares I need to use?
the answer is vanitygen.
you can find binaries or can compile yourself
here (my suggestion is compiling yourself since that's a address generator thing, you shouldn't trust binaries)
a friendly reminder though, more personalized chars means more CPU time. examples like 1111111111111111111114oLvT2 is just impossible for the current hashing techniques.
