The drawing illustrates an economical method of constructing electronic module enclosures with sealing properties. It is considered particularly, but not exclusively, useful for protecting program cartridges (e.g., game cartridges) offered as personal computer attachments. Cartridge 1, enclosing a program card 2 which plugs into connecting receptacle 3, contains elastic material 4 forming a protective seal for the card. As indicated in the lower left view 5, the seal deflects to permit connection of the card. The seal is formed by molding a low density elastic material -- e.g., urethane foam -- into the cartridge enclosure, leaving a small clearance space 6 for the program card.
