Just wondering what style I have (MM cart with different serial than mainboard, power brick, and audio board; mainboard has 1985 on it) and what's with the doubled up chips and jumper wires? So it can run the other system 1 carts? There's one of these wires off and want to fix it to make sure other carts will work ok. MM works fine playing and test modes.

If these wires are normal, can anyone send me some pics of my first photo so I know where I should attach to?

Thanks for this great forum. Great community with lots of help!!!

That is a TTL main board (the LSI doesn't have the white strips).

Thanks! That's what I thought. I ended up taking the board to my uncle who does this work and said that this looks like factory stuff -- scary all those wires are all over. Anyhow, we soldered the wire back to where it was supposed to be without drama.
