Odyssey2 Game Cord Replacement Hack
Replace that non-standard TV cord on early Odyssey2 units
with a regular RCA type cord that will work with most TV/Game Switch boxes
'F' Connectors. This procedure can also be used to replace broken cords
on units that already have
Note: This hack will not work with newer video input jacks on modern
TV sets. You must use a TV/Game Switch box or TV/Video 'F' Connector!

Info on this Hack:
- This hack is for the first generation Odyssey2 and some of the
second generation Odyssey2 units that have a non-standard
style TV Game Cord (see picture). This type of connector will only work on
special switch boxes that were included with the original Odyssey2 consoles. Using
this 'Hack', you can use most newer switch boxes or the RCA 'F' adaptors.

Original TV/Game Switch for use with
Replacing this cord will allow you to use standard Atari
compatible TV/Game Switch boxes or TV/Video 'F' Connectors.
- Note that this hack involves replacing the original TV Game Cord and will
involve opening up your Odyssey2
unit. This is a fairly easy hack, but please use caution when doing this.
- The only tool needed for this hack is a 1/4" Socket Wrench!
- Parts need for this hack are:
- An RCA style video cord from another older game
system, or a current RCA style video cable. NOTE: many current RCA
style video cables may be shielded for better video quality, but they
may not fit properly inside the Odyssey2 unit (it is a rather

- Of course, you will also need the TV/Game Switch, or you can use a Phone-to-F
Adaptor. It depends on your needs. The Switch allows you to attach
an antenna or cable TV, the Phono adaptor only allows for the game
system. Each has it own pros and cons - this decision is up to you!

Game Cord Replacement Hack!
- Disconnect the power and video connector from the Odyssey2 unit.
- Using a large flat surface to work on, place the Odyssey2 unit
keyboard side down.
Remove the three hex screws on the back of the
unit using the 1/4" socket
wrench. (Show above with red circles).
Place the screws were you won't loose them!
- With the screws taken out, remove the back cover from the unit. It may take
a little bit of force to remove this, especially if the unit is somewhat
dirty. Place the back piece on the side for now.
- On the inside of the unit, you will see a metal shield covering the inside
components of the game system. Do not mess with anything beside what
is in this guide (unless you feel the need to possibly ruin your odyssey2 game
- Focusing on the upper right of the unit (while it is upside down), you will
see where the Game Cord attaches to the Odyssey2.
- Remove the hex screw holding the Game Cord to the Odyssey2 unit.
Place the screw on the side again where it won't be lost.
- Carefully remove the Game Cord itself from the unit by pulling it to
the right, away from the game console. Note that this may take a bit
of force, since
the connector has probably been on for over 20 years! Just be carefully
you don't break
anything or hurt yourself if the connector let's go suddenly.
- With the cord removed, take the plastic strap off of the game cord (this
was the part that was held in with the hex screw). Put this on the side along
with the hex screw for now.
- Dispose of the old game cord however you wish! You can keep it for prosperity,
or in case you wish to revert back to that old crummy connector, but
I leave that up to you. Personally, I would hold onto it until you are
sure the hardware hack works. It should, but I make no 100% guarantee
that it will work with every Odyssey unit out there. It did work with
the two I tested it on, but life doesn't always go according to plans!
- At this point, take out the cord that you are going to put in place of the
one you took out. As mentioned above, you can use any old style game
cord that has an RCA plug on both ends. Many older systems came with
one that was not permanently attached to the unit like the Odyssey2,
such as the Intellivision or Colecovision. You may find this cord at you local electronic
store too. You can also use more modern shielded video cables, but note
that the connector may not fit into the Odyssey2
unit, as there is not a lot of room where the connector plugs in (Don't say I didn't
warn you)! Use your best judgment on this, as it is your Odyssey2
Regular game cord - should fit well, but may have some interference on some TV sets,
as they are not well shielded.
Modern video cable - works great, but will barely fit inside the Odyssey2
unit. If in doubt, make sure you can get your money back if you buy one of these!
- Take which ever type of cord you are replacing the original cord with (A/V
type or Regular old-style RCA game cord) and plug it into the jack on
the inside of the Odyssey2 unit. Make sure the cord in firmly attached!
Note that the more modern A/V style video cords will fit very closely.
Be careful not the bend the A/V cord too much or it may break (in the
picture below, I unscrewed the connector sleeve to make the cord fit
Put the plastic strap from the old cord onto the new cord, loop it
around as the original cord was, and re-attach the strap with the hex screw
using the socket wrench. Then squeeze the cord into the slot where
would come out the backside of the unit.
Note: With a newer A/V style
cord, you will have to use a knife or dremel tool to make the gap
that the cord comes out of is wide enough for the new cord to fit.
Be careful if you do this, and make sure you widen the gap on the
top and bottom
halves of the case (see red box in picture below)!

- Test the unit before putting it back together. Carefully
put the back cover from unit temporarily back into position, making
sure the replacement TV cord doesn't get pinched. Holding the unit
by hand, place the unit upright on a
flat surface. Put a cartridge into the unit, plug in
the power supply,
and attach the
cord to the TV. Turn everything on and try the game out. If it works
and looks good on the TV, outstanding! If not, backtrack to see if
you missed something. If nothing was missed, then I would recommend
in place and just dealing with the old cord, or buying a new unit.
This should be the exception though, as this hardware hack have been
proven to work, but I cannot be certain it will work on every early
- If the test worked, then turn the unit off and unplug the power
cord, TV cord (from the TV), and remove the cartridge. Turn the unit
back over so the backside is facing up. Make sure that the new
cord fits and that the cover is properly in place. Then take the
from step 2 and screw them back into place using the 1/4" socket
wrench. Don't tighten them too much, or you may strip the plastic
inside the screw holes! Flip the unit over and your done! You can
do a final test with your favorite game, just to double check that
everything is fine! Hope you enjoy your replacement cord, and may
it last for a long time.
