Getting A PS3 in 2023

Last month, my uncle gave me his super-slim ps3, he didn't want it because he described the controllers saying that they were drifting. He gave us the console, 4 controllers (1 black,1 red,1 transparent blue,1 pink) and 8 games. It didn't came with power cable but I found out I was able to use my old ps4 power cable and lucky enough, it turned on first try. but I didn't have a cable to connect the controllers to the ps3 so I had get a new one. after I got the cable, I connected the controller on the ps3 and then it started pressing buttons on it's own. I tried using the other controllers but they were all doing the same thing. I learned that you can use your Dualshock 4 on the ps3 so i was using that for a little while. Then I found out how to fix that problem. So as of right now, I was able to fix 3 of them.
