What is the Oldest Video Gaming System you own?!?

Hi! I had and owned a Family Computer before. The games are sort of like huge microchips that are encased in big plastic that has the feel of a thick floppy disk. Its where I play Mario, Donkey Kong and otehr video games. Its my very first video game console. Sad thing is that one of my neighbors borrowed it then they moved and I never heard from them again. It was still functional when they left and if I still had it I never would have bought my Playstation 2. I dont mind playing in old video game consoles as long as they still do the job. My cousin has a Gameboy. The slim one. I think the first was the big bulky one then this slim one came out. I was addicted to it and I play Mario in it too. I think tis still functional and I know that she doesnt use it anymore. Id like to have it for myself but I think she's letting a friend borrow it. I dont mind if I dont have it, I still have my Playstation 2. Only problem is that is broken but maybe it jsut needs a little lens cleaning otherwise Ill need to replace the lens itself. Have fun in using your old videogames^_^

I have the first nintendo,sega genesis,NES
