This is my original Genesis I bought in like '92(?) with one of my first paychecks from my first job at Chuck E. Cheese's (yes I'm fucking old).
I thought I sold it years ago but found out it was sitting in one of my mom's closets, so I bought a few cheap carts and hooked it up to a crt I keep around for just such occasions. It still works!
I am so goddamn happy, I just had to share and I figured you all might appreciate that.
Sounds great, but I'll have you know you can buy a cable to connect to composite. That's how I hooked up mine to my modern TV. Works great. I have an old CRT too, that's where it's hooked up most of the time.
