Yes, I got the color bars when just connecting it.
It’s a good time while I’m here to update. I contacted Mike and my TINK is on its way back to him for a refund, my new Retron77 is setup and working like a champ, and my beautiful 2600, games and Harmony cart are packed away (as is my TI-99/4A). Hopefully one day I can resurrect them, or at the very least, display them. 🙂
