Schematic

This is the more advanced version of the Supercart. It has 5 solder jumpers that allow it to be used for a wide variety of configurations. U2 can hold either additional ROM, or a RAM chip. As can be seen in the left picture this board can also be used with certain chips not populated for simpler carts.
