Black Box 3 - What is this thing, and is it worth anything?

[Black Box 3 - What is this thing, and is it worth anything?]

Do you have any photos of the carts you have? Do they look the same? I'm still wondering what console it's for, and if it's worth anything. Could it be Atari 400/800?

I would be interested to trade or sell the cart if there are any bidders, as I don't really have any use for it myself.

Have a look at the video - on the back of the cart there is the text "T2000 Atari" printed on it.

Hello!

 

Recently I found a strange Atari cartridge at a flea-market in Poland. It has the name "Black Box 3" printed on it.

Does anyone on this forum know what this is? And is it worth anything?

After Googling "Black Box" I found some information about some sort of cheat module for Atari's computer range. But it doesn't look the same as the cartridge that I found.

Here is a Youtube-video I made, where you can have a closer look at it:

I hope someone knows something about this thing!
