Here's a little anecdote on how I got my PS1.
My dad walked into my room and said he found a cable box/VCR or something sitting on the curb waiting for bulk trash on top of some old trash and furniture. He handed it to me, and little did we know, SCPH-1001 from November 1996. It was raining that night, so he said just open the lid and set it upside down for a few days. Did so, and plugged it in... and it booted up! I took some alcohol to the lens on a Q-tip, and now it's a fully working PS1. How incredible. I also obtained the world's first DVD player this way. You never know. If you see an electronic-looking box on the curb, take it! Where I'm at, all bulk trash goes to the curb, it might be different or even illegal where you are (like in NY). But here, it's legal and if I see tech, i take it! XD
