Sega Master System (SMS), Sega Genesis and Atari 2600 to Intellivision controller adapter
Allows the above controllers to be used on Intellivision 2 or Sears. Also works with Intellivision 1 if you add db9 ports to it.
SMS and Genesis support 2 button operation, 3 if you count pressing both action buttons at same time to activate (Intv) lower right action button. Ideally adapter is for use with games that normally use one or two action buttons. Atari 2600 controller supports 1 button. Adapter supports 4-way and 8-way controllers. Adapter does not support 16 directions. Adapter has built in keypad for Intellivision.
In general the Sega Genesis 6 button controller seems to work best for Intellivision games, outside of using a gated arcade joystick.
Price is $70
