Intellivision I and II, as often consoles of that time, only have the RF output to connect to a TV, but what if we wanted to use it on a new TV or monitor? Let's see how simple it is to take the composite signal.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Here on the right you can see the inside of the console, the change is already applied here !. Let's see later how it was connected and how to build it. To remove the motherboard it is necessary to remove the black screws, they are 4, 2 on the pcb and 2 on the cartridge connector, then lifting the pcb from the bottom will remove it from the body.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The first thing to do is to remove the joypads and remove the 2 screws at the bottom, then simply lift the cover from the part where we removed the screws.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Don't worry, no wire to cut, well if you want to exclude the modulator you can cut or unsolder the second one starting from the top (marked with a red arrow), it is not necessary, I tried and the video signal is also good with the modulator.
In case you see if it gives you problems. The 5V positive power supply can be taken from that red arrow next to the capacitor or from other points on the board, in the photo I used that pad.
In the modulator there is a voltage of 12V so to use that it should first be lowered in order not to be too high on the video output.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Now that we have all the signals we need, let's go ahead and see the schematic for amplifying the signal.<\/p>

PS. For Intellivision I it is the same thing.<\/p>

This is the scheme of the amplifier, unlike the one used in the Atari 2600 this has 2 stages to have a greater amplification of the video signal.<\/p>\n

We have arrived at the end, the modification is complete, now all that remains is to pass the cables (I recommend the hole where the modulator connector is) and have the video and audio arca external to the console.<\/p>\n

ENJOY YOUR MOD!<\/b><\/p>
