Hardware Hacks - Play Coleco Branded Intellivision Games on Intellivision 2

This is a pretty simple mod, almost anyone can do it. All you have to do is hook up a momentary contact switch between pins #38 and #40 on the cartridge port. Take the top off of the Intellivision II, and with the front of the unit facing you, count from the back of the unit, to the 3rd and 4th pins of the cartridge port (the row of pins that you can get to easily, not the lower ones). With the system all hooked up, pop in a Coleco cartridge, turn the unit on, and take something metal (insulated or not, it won't shock you) and touch the 2 pins together just once, then pull away. The game should then come on. If it doesn't, just try again.

Mounting the momentary switch is a pretty simple installation job. Head down to your local Radio Shack and pick up one that tickles your fancy. Drill a hole in your case where you want to install the switch (you might want to keep it a little farther away from the cart port, it'll make it easier to access if you have an ECS or Intellivoice installed as well), hook the wires from the switch to pins #38 and #40, solder it down (if you want to, not 100% necessary, just make sure no wire is touching any of the other pins on the cart port, you may short something out).

Pictures will come soon, as soon as I have time to do this mod myself. 8*)
