Intellivision A/V Mod Installation Guide

1 Intellivision A/V Mod Installation Guide This document will guide you through installing your Intellivision A/V Mod Kit to your Intellivision I, II, and III game consoles. Installation is basically the same with varying models. We will show the different 5v source for Intellivision II. Step-by-step guide will show you the detailed instructions; please carefully follow them. Important Note! These old consoles do have large capacitors inside and they need to be discharged before doing any job with the electronics of them. Otherwise, you may get shocked by accidentally or unintentionally touching them. To avoid such a situation, please leave your Intellivision game system s On/Off switch at the ON position for at least 5 minutes with the power plug off the electricity source. Please do not skip this stage! Disclaimer: Though this job is a pretty easy task, it requires that you do some soldering of some wires and connections. If you are not skilled with a soldering iron, please have this installed by someone experienced! I cannot be held responsible for any harm you do to yourself or to your Intellivision game console. Tools Needed Soldering iron, solder, and solder braid X-Acto knife Drill with 1/3 and 1/8 drill bits Needle-nose pliers Philips-head and flat-head screwdrivers Hot glue gun and hot glue stick(optional)

2 Step 1: Open your Intellivision by unscrewing the six screws shown below.

3 Step 2: Again, unscrew the six screws off the platform housing the cables of Intellivision controllers. Follow the arrows for this. Step 3: Carefully unplug the power wires. It is a pity that, years don t behave these systems fairly and such connections may become loose or weak. It s highly recommended that you should really be patient with this stage.

4 Step 4: Now, remove the controllers from the motherboard by simply pulling the plugs away gently and patiently. Using some piece of solder braid, de-solder the RF shielding plates off the motherboard of the system. For Intellivision II and III, you can skip this job as they don t have a shielding around. Step 5: Next, solder the wires to the locations shown below. The wires are labelled on your Intellivision A/V circuit; just match them. 5 volts on the system s motherboard is the first pin of the power flexcable counting from the bottom. Pin 4 or any metal framing the motherboard is your ground ; solder the GND in wire from your A/V circuit here. This kind of flexcables are sensitive to heat; please don t heat them more than needed while soldering on them or nearby. UM RF Modulator has the video and audio legs. Take your V in and A in wires from your A/V circuit and solder them to the legs shown below. Again counting from the bottom, Leg 1 is video and Leg 3 is the audio source.

5 Here is the diagram for Intellivision II. You can solder your GND in wire to any open point at the boundary of the motherboard; and you can pull your 5 volts from the light green trace shown below. Note that IC names can sometimes change as AY into AY or AY and the AM9114s into 2114s. Step 6: Use your needle-nose pliers and bend the piece of metal at the black shielding as shown below. This will be our gate for the wires going to the A/V circuit.

6 Step 7: Now, solder back both of the RF shielding plates and make sure your previously soldered inner wires are not smashed in anyway. Your result for this stage should look something similar to the one below. Step 8: Now, remove the power supply module as shown. It has 2 screws only. Then, pass the remaining wires of the A/V circuit through the canal below the orange cardboard. Also, now is the time to mount your A/V Out connection jacks on your case. Carefully measure the final location and open the two 1/3 holes for the Audio and Video jacks with two 1/8 holes at the sides for the screw set. Use your flat-head screwdriver to turn the screw while holding the nut behind with your needle-nose pliers.

7 Step 9: Solder your GND out wire from the A/V circuit to both of the jacks outer terminals. Your V out wire should be soldered to the center terminal of the yellow jack and A out wire to the center terminal of the white jack. Again, refer to the picture below. Step 10: Plug the power wires coming from the motherboard to the power supply unit in the way you found them at the beginning. Attach your double-sided tape on the back of the circuit and then, to the place shown. Make sure you place the A/V circuit as next to as possible to the screw hole shown on the picture. Otherwise, it may be smashed by the piece of plastic coming over it when the case is closed. Don t forget to clean the place before doing this. You can, optionally, use hot glue here to add strength. Do not let the assembly get over-thick, though.

8 Finalizing... Now, you re set. It s always a good idea to check the functionality before making the thing into one piece. Connect your Intellivision to your Tv via A/V cables and see the improvement over old snowy, wavy, and noisy RF connection. If your mod doesn t work, go back and double-check what you did so far. Also, cleaning the cartridge port and the edges of your game cartridges may help. Sometimes, cartridge ports may get filled with dust and also, game cartridge edges may catch grease or dirt. If your mod works, you should have a nice and clear picture with noise-free sound. Now, you can reassemble your Intellivision. Have Good Gaming Sessions!
