I'm looking in to that very thing here in Taiwan. I am hoping to make a large quantity of blanks for future use, but need to get a few empty cases to provide to the manufacturers to make molds from. Could someone mail me with some info on standard case sizes and which games used them? Also, what about the possible limitations of certain cases. I'm dumb on the technical side of the Atari world and could use some assistance. Any mail appreciated.

The boards are great, Joe
... but does anyone know where to source blank plastic cart cases?
