Masterplay Atari 5200 interface

Description

Masterplay Joystick Interface for the Atari 5200 game system. This unit allows a standard 2600 joystick to be played on this system instead of using the 5200 controller. Interface allows a 5200 controller to be paired with it in the event you need the keypad inputs with a toggle switch to switch between the two. Unit fully tested and works great. Only the unit no box or manual. I included the manual in the photos. Comes from pet, bug free home.
