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 :)

Funnily enough, I still have this project on the books, I'd better dig it out and get on with it myself.

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.

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