Intellivision 1 Composite Video Install
The Step-by-Step Guide to install the Intellivision Composite Video Out Modification
(Click on the image to view a higher resolution of it)
1. Make sure that you have your Intv1 and modification board. Cable length fits either Intv 1 and Intv 2 consoles. If the cables seem to be too long for your console and prevent the mod from fitting easily into it, cut them down to the size you need.
2. This I what
you need
a) A drill (to create the holes for the composite jacks)
b) A 8.0 drill bit (note: this is not a U.S.
measurement size)
c) A soldering iron
d) Solder wire
e) A Phillips screwdriver
f) A knife (not shown in the picture)
g) A small pair of pliers (not shown in the picture)
3. Turn the console upside down and unscrew all six screws that hold the cover. Turn the Intellivision again and remove the cover.
4. Unscrew all six screws that retain the joypad attachment.
5. Remove it.
6. Locate the power supply unit and detach the white and the blue cable at
the right side of the board. Be sure to memorize polarity of the white cable.
7. Detach the
joypads from the main board. Make sure to memorize polarity! You can help to
ensure correct polarity is maintained when reassembling by marking the cabel/connector
and the PCB with a black felt-tip pen.
8. Put the housing and the joypads aside. You will need to open the black
shielding now. There are nine soldering points that hold the shielding in place.
9. Gently push the knife between the main board and the shielding and lever the
blade down a bit as shown in the photo. Break the soldering point with the
soldering iron. Proceed until all soldering points have been desoldered. Check
whether the small metal plate of the reset button is still in place. It tends to
fall off...
10. Remove the black shielding and locate the RF section.
11. Solder the inner wire of cable “V IN” from the mod to the wire on the right
side of the RF section as shown on the picture below. Solder the “A IN” cable
from the mod to second wire from the left that leads into the RF section.
12. When the cables are correctly soldered to the RF section put the
shielding back in place.
13. Now comes the hardest part. Drill two holes in the housing; choose the
position shown in the picture, next to the power plug. Be sure to use an
appropriately sized drill bit, if you are unsure which size is correct, use a
smaller sized bit first. Attach the rca connectors carefully
14. Tighten the RCA socket locking nuts. Solder wire „V OUT“ to the yellow
RCA connector and „A OUT“ to the black RCA connector. Attach the wires as shown
in this picture.
15. Put the main board back into the casing, connect the hand controllers to
it (POLARITY!) and the blue wire to the power supply PCB. Solder the red wire
„+5 V“ from the mod to the white power cable like shown in the picture. Choose
the topmost connector and do not damage the other conducting paths! Connect the
white power cable to it‘s jack on the power supply PCB, ensuring correct
polarity.
16. Solder the black wire „GND“ from the mod to any of the soldering points
that hold the black shielding of the main board.
17. Your console and the mod should now be properly connected to each other. Put
the joypad attachment back in place and tighten the screws.
18. Close the cover again and tighten all six screws you removed in Step 1. You
now have the best video output for you Intellivision I!
OPTIONAL - Improving picture quality even more:
Take any game cartridge that uses the original title screen (the one with color
bars). Power your system on. Turn the potentiometer with a very small pair of
pliers. Adjust the picture until it looks best on your TV. You should have even
better video output for your Intellivision I now!
The RF output will still be functional if you ever have the
need to use it.
** ALWAYS ** make sure you have the video wire connected to the YELLOW
composite jack. You could cause damage to your TV if you have the wires
reversed.
Warning! Your game system has to be powered on while the cover is open in
order to perform the adjustments. Please ensure that all safety precautions are
taken to prevent contact with any powered cables or parts of the power supply
unit. OK? Here is the interesting part.
It is possible to adjust colors and the picture quality of your Intellivision I
console. There is a tiny potentiometer on the main board that controls these
parameters. This is what it looks like:
DISCLAIMER:
This mod has been carefully designed and manufactured. It has proven to work. To
my knowledge, it does not harm your system.
Nevertheless, I cannot be held responsible for any damage of your console (and
yourself), when you install it. You open and modify your Intellivision at your
own risk. Please make sure that your console is not connected to any power
source whenever the cover is removed.
Study all information given in this installation guide about how to install the
mod in the video game system carefully before you proceed. If there is anything
not absolutely clear to you about this process, do not install the mod.
