Sory if this is a stupid question - I have been "gathering" carts for years, but never really "colelcting them", payign attention to variations and conditions and whatnot. I have two copies of the Atari picture label Missile Command cart. One of them has the standard, all-caps end label like all my other Atari picture label carts. The other one has an end label which is in all lower case. The font looks the same as the end label for the text label carts, but without the silver border. This is the only cartridge i have that has this lower case end label. Is this a very common variation, and what other carts had this kind of label? I just noticed it the other night, and was a little surprised it had escaped my notice for so long.

I am working on bulding an all-in-one controller for my 2600 that will contain a joystick, paddles, and touchpad. I have taken apart a joystick and paddle and gotten the pinouts for them, but unfortunately I no longer have the touchpad I got with Star Raiders. I seem to recall it used different resistors on one side of the matrix, but I need to know what vlues they are, and what the pinout of the controller is. Hours of google searches have not brought me any closer to finding a schematic for it, either. Any help will be greatly appreciated!
