Hi! Guy staying with me found an Intellvision 2609 and some games at the dump, What a rescue! Figure, why not Composite Video Mod it? Well, found this site: wiki.intellivision.us and thought I could use it and remove the rf module, and place the circuit board there. Blank Screen, searching internet and various people have had similar problems removing rf module, and with it in circuit, causes some ghosting. I ain't no professional, but I know enough to be dangerous, and start hacking rf box apart by pulling components off one bit at a time, soldering back on with it disturbed the image. So, things are good, but I screwed up and the image is too bright and washed out. when doing this, do it one part at a time so's one knows what part did the rick or not... :/ Anyway, I created an rf module shunt circuit Intellivision RF Module Shunt Circuit for 2609.pdf I'm not sure what type of zener diode that is, but it's marked B2 5 and a regular diode didn't work on mock up circuit... Also, I included a Filtering Coil, but I don't think it's needed. Also of note, I tried this circuitbut doesn't work :/ (The internet doesn't lie, right?) Also tried that circuit in front of the intellivision wiki one... I also finished a Atari 2600 Composite Video Mod using Ben Hecks Modified or revised circuit... and looked at other circuits and realized that the outputs from these video chips go through a resistor network and feeds into at least one NPN transistor. Maybe the Intellivision Wiki one can be revised or simplified and include a resistor network cutting original traces ... Anyway, TL;DR: I ripped parts out of rf module untill I had this basic circuit. Now got Composite Video with minimal ghosting. Posting results to share with others. Some more shamless pics:
Hello all, If anyone is looking for a flashback controller adapter for the Intellivision model 2609 or similar version, I have some for sale. They are a little more expensive to make than the other adapter so I'll be charging $15 for one and $25 for two. Those prices are including shipping in the US. These adapters do require you to open you machine for installation but it's only 6 screws and then it's plug and play after that. Here are some pictures.
