I mined in early 2010 with a cpu miner and just found my keys after forgetting all thease years, no joke need info please

So a few things, what was the mining program from the devs back then? I remember a pop up kinda like a dos window and it dispalyed the key and said somthing like write this down we will not give it to you again… I also remeber a pass sentance proram that could be used to recover somthing if you entered in you full sentace string..

I have been out of crypto since I mined a few blocks way back then and I have my keys so do i just download and sink the wallet first? remeber I did this long ago and was hoping to located the mining program from way back then to read the readme and refresh my memory. Also back then you could contact a dev to help you,, thanks in advance for helping out a old man trying to pay a few bills.
