This is a 1983 ad for five Atari 5200 games by CBS Electronics. The games advertised are GORF, Blue Print, Wizard of Wor, Mountain King and K-Razy Shoot-Out.

GORF is a port of the arcade game of the same name and is a single screen shooter consisting of multiple stages. It's kind of like a mash-up of Space Invaders, Galaxian, and others. The Atari 5200 port is a pretty good port. Versions were also available for the VIC-20, ColecoVision, Atari 2600 and Commodore 64.

Blue Print is also an arcade port and is a maze game. Versions were also available for the Atari 2600 and Commodore 64.

Wizard of Wor is another arcade port of a maze game. Versions were also available for the Atari 8-bit family, Commodore 64, Atari 2600 and Bally Astrocade (though it was retitled 'The Incredible Wizard' on the Astrocade).

Mountain King is a platform game and the first on this list that wasn't an arcade port. Versions were also available for the Atari 2600, ColecoVision, Atari 8-bit family, Commodore 64 and VIC-20.

Finally, K-Razy Shoot-Out, while not a direct arcade port is a clone of Berzerk. It was first developed for the Atari 8-bit family with the Atari 5200 version following later.
