Atari XEGS cartridge-tech

This is a picture of an XEGS ROM-cartridge ("Tennis" [RX8042]). It consists of two NCR 2364-30 and two capacitors.

OK, the following isn't quite tech-related, but interesting anyway: Atari seems to have produced (and cased) so many XL/XE games over the (Warner) years, that they still had to use them in the year 1987...as you can see, this is a 1987 "Tennis" (RX8042), but still with the "Warner" metal-shielding on its back!
