Atari C025474




This is non-bankswithed 32K cartridge. The 32K is borken up between 2, 16K ROMS and appears in the address range $8000-$FFFF. If you look at the schematics you will notice the both roms are wired indentically meaning that internally one ROM must have an active low chip enable and the other an active high. Also notice the two large solder pads to either side of the bottom ROM. These are connected to ground and were probably going to be used to put a shield can over the ROM.
