Upgrading a 7800 for modern times - Mark - 08-22-2026
I recently purchased a 7800 via eBay after being successful with a cheeky bid. I've never had or used one but always interested in the concept and have had many other ataris over the years from a 2600, 8bit computers and a few ST's.
Over the coming weeks I will be modifying the console to allow me to use on a modern TV, look at what repairs, if any are needed and look for a multi cart that addresses the pokey challenges of a couple of cart having pokey chips installed.
I haven't decided if I should video the progress or just document with some photos, let me know what you'd like to see?
Cheers
Mark

I have all the parts now to move forward and need to find a few of my tools such as a solder sucker. Recently moved and still have a lot of my stuff in boxes... Maybe I should have focused on unpacking before this but here we are
I need to find a decent pair of wire snippers, pliers, solder sucker, solder iron etc. Think I have all bar a small wire snippers but let's see how it will go. I will try and video the process but that is all new to me so bare with me...
Wish me luck!

Unboxed and had a closer look at what I've purchased.
Console and games look in nice condition but the power cable seems to have an issue? What's under the tape I wonder?!

The tape was just tape, no hidden surprises thankfully!
Wasn't easy getting the RF shielding off but got there in the end and now for the brave part in removing some components and fitting the composite mod.
Looking a good clean example
