Atari 5200 cartridge-tech

Ever wondered, what those little imprinted numbers on the the top left on the labels mean (inside the red square)? Well, it's quite easy: the first two digits tell us the WEEK of production, the third digit tells the YEAR of production, i.e. this "Qix" (CX5212) was manufactured in the 16th week of 1983. The same "coding"-system was used on several 2600 cartridges.

This is a picture of a 5200 ROM-cartridge ("Pac-Man" [CX5208]). It consists of two NCR 2332-30, one capacitor and one diode. The metal-shielding has been removed.
