In the review I watched, Mike stated that the power supply should be under 500mA... fyi

Just curious, has a schematic for the MBX ever been located? Thank you,

Yes, I have, and it doesn't work that way either. In fact, it doesn't work that way on a non-2.2 either. I tried it again just to be sure, but I remember that from back in the day. I always had to plug the cart directly into the TI to play the game. It never did work with anything between it and the TI console.

Unfortunately I do not own a Mini Memory cart. I may be able to borrow one. If I can get my hands on one I will give it try and post the results.

My 2.2 is and original mobo, not a QI mobo. Even with that being said, I am sure that the carts are fully seated and both of my Miner2049er carts have been tried multiple times. Both carts work in non-2.2 consoles. The expansion port in the 2.2 works. I have operated a speech synthesizer as well as a NanoPEB and a CF7+. I have not connected a PEB to it.

I have only one(1) 2.2 console and two(2) Miner 2049er carts. Neither cart will work in my 2.2 console. When in place, the menu only presents the TI BASIC option. Any ideas why this would be? This is certainly not an issue specifically for me as the 2.2 console only came into my possession recently and I have other consoles I use regularly. I was under the impression that it (Miner) would work. When it didn't (using either cart) my curiosity was peaked.
