I’m not a fan of modding the classics if it can be avoided, but the RF only output of my Atari 2600 was rendering it pretty much useless - life’s too short for RF. So I put my morals aside and bought myself a composite mod kit from http://www.vintagegamingandmore.com/, and got soldering. Excellent instructions are available on the website, and the provided components were OK(ish), but it was still a reasonably challenging mod because of the compactness of the ‘Junior’ model. It was worth the effort though, I would say - the image quality is very good. I can’t ever seem to take a decent photo of my CRT, but there are ‘before and after’ examples provided on the website which accurately show the sort of improvement you can expect. Something you can’t expect, of course, is that the 2600 will be anything other than a very crude piece of hardware. I’ve spent a lot of time recently on my C64 which made the limitations of the 2600 all the more pronounced. The sound capabilities in particular can be grating – it must have driven parents nuts back in the day. It’s still a lot of fun to play though – Space Invaders, Pac Man, Adventure, etc still suck me in.
