My email is thedrx@gmail.com, he can feel free to either contact me directly or go through you, it's fine by me either way. (BTW I'd prefer if you contacted me by email)

I can't reveal much about the source other than it was someone who claimed to be a Sega employee and had some EPROM carts, including three copies of Tetris, which I got off him. He wished to remain anonymous.

I can take some pictures, but not right now. I have the two Tetris stashed somewhere where I don't have easy access to it. I'll get to it in a few days/weeks though. One looks similar to yours and one is a shorter cart. I might have pics of the shorter cart somewhere, I'll have to look.

Can you reveal who the interested party is?

Thanks!

Luke
