No smart alecks, I am not looking for "use as drink coasters" or any arts & crafts suggestions. I really would just like to mail them to whomever for approximate cost of shipping or a little more so I don't just throw them in the garbage. I recently went through a box of loose cartridges and have seven that are non-working: 3 are Atari-style, 3 are Activision-style, and 1 is Turmoil.
While I'm at it, for some reason long ago, I salvaged the ROMs for Maze Craze and Gopher from physically broken cartridges. If anybody wants those for some reason.
Thank you!
