Its been over a year since this project was started. I'm going to try and get this project finished in the near future. I've found a few of the bits yesterday.. Still need to find the PCBs.. So might have to order some again. I really want to get my 2600 back together and have some fun with it :)

I've built these using veroboard, they work well enough, but time to get on with the exxos one :)

So many projects and so little time :( I want to close up all these unfinished projects so I can just concentrate on the remake motherboard.

Found the PCB with parts listed..

There are a couple resistors I am not sure about at the bottom.. more of a "suck it and see" type thing. So some experimentation needed no doubt.

I've got a couple of 2600s lined up for when you've finished :D
If it ain't broke, test it to Destruction.

You need a various pcb box. Icky probably has a label you could use once you've got one.
