AV Mod #2 Completed - Atari 7800

Just completed my second console AV mod - I now have an Atari 7800 that uses composite video! Picture is far, far better than RF, and the audio is much nicer too.

Sadly, I'm having odd issues with the controllers now. I'm assuming my controllers didn't just arbitrarily break on me, so now I think I need to investigate what I might have accidentally screwed up in the process of doing the mod. Hoping that my mod installation doesn't end up being a waste of time due to killing the console. :(

    And it's fixed! I had just accidentally jumped a couple resistors in the process. A quick continuity check of areas I touched yielded this result - cleaned up the solder, tested it out, and we're all good!

    I am ready to start recording DIRECT FEED for Atari 2600 and 7800 games!

    This kind of thing always reminds me how much of a "plug & play" bloke I am: give me the innards of software & I'm fine, but if it aint'a "plug this in there" for hardware I'm scuppered! I can open a box and clean the dust away. :P

    I was the same way when I bought my pinball machine - but I also knew I was going to HAVE TO learn to keep it working. It worked well as a forcing function - now one Haako soldering station, one Haako desoldering gun, and lots accessories later, I'm doing things like this!

    I'm definitely not knowledgeable enough to do things like design my own circuits or AV mods or the like. But I'm far more comfortable doing soldering work in electronics.

    I am still nervous about AV modding my Intellivision though, after seeing some videos of others doing so. The heaps of solder on the RF shield tabs and the cheap ribbon cable that comes apart if you look at it wrong definitely don't make it look fun.

    I've bought some "needs repair" stuff thinking it'd give me the push... It hasn't! I just bought a working unit instead. :P Repair stuff just gets pushed towards my old man - now in his 70s, he's not about to fix the stuff.

    I need to do this too. Maybe when work slows down ill grab a kit and get cracking.

    Depends on the circuit board you have to solder. Some are resistors so close together, I don't know how some people do it. Takes a steady hand that's for sure.

    The desoldering gun I have made doing this mod a heck of a lot easier - resistors aren't hard to remove when you can just put the end on the solder point, wait a second, and then press a trigger to suck away the solder. :) It also meant I didn't have to cut a single thing, so other than the holes in the case, I could theoretically reverse everything I did.

    Definitely a must-have tool for anyone doing regular soldering work.

    I don't even have one yet. And honestly, I'm not in a hurry to get one. Other systems I want to pick up first.

    Great Work.

    I love to see original hardware being used again.

    And if it can be helped by working in a modern way without

    changing what it really is, that is truly the way for it to survive.
