Disclaimer:
This mod has been carefully designed and manufactured. It has
proved 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.
Many thanks to David Harley and Grant Ferey for the revision
of the guides. The layout design was made by Franco Ricciardi.
Thanks to Joe Zbiciak and Tim Lindner for creating the original
design of this modication.
Feel free to use all pictures and information for any Intellivision
related purpose, but please indicate its origin.

Make sure that you have your Intv2 and modication board and
a well lit work area. You will require aproximately 45 minutes to
complete this modication. Cable length ts either Intv 1 and Intv
2 consoles. If the cables seem to be too long for your console and
prevent the mod from tting easily into it, cut them down to the
size you need.

Locate the power supply and unscrew all three screws. Turn the
PCB upside down.

Solder the red wire „+5V“ from the mod to the power supply PCB
as shown in the picture. You should attach the wire to the third
soldering point to the left of the notch. The correct soldering point
is wider than the others:

Take care to ensure that the wire is soldered to the correct position:

Drill the holes in the housing for the RCA connectors.
*** WARNING *** The holes needs to be precisely centered as there
will be little space remaining above and beneath the holes. Be sure
to use an appropriately sized drill. If you are unsure which size bit
is correct, use a smaller one rst.
***Note*** Your mod might be delivered with three RCA jacks. It is
recommended not to use three RCA jacks with an INTV II console.
You will nd a positioning device on page 17 of this guide to help
you nding the right position for two RCA connectors.

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 the picture.

Place the cables under the Intv PCB and put the the Intv PCB back
inside the chassis. Place the mod board in the open area next to the
composite connectors. Tighten the four screws that hold the Intv
PCB down.

Return the cover by angling it so the two rear hinges engage. Close
the cover down gently and tighten the two screens. Attach the con-
trollers.

Use the positioning device shown below to nd the correct positi-
on for the RCA connectors.
Print the graphics at full size and check whether the scale is cor-
rect using a ruler. Attach the positioning device to the housing of
your console using an adhesive tape and puncture the middle of
the crosses with a needle. This is where the holes should be drilled.
