I found a publication online which would help me and others develop a program or game to run on the 2600, and it was called "Atari Programming for Newbies". It was available in PDF form, so I got a hold of it, and printed it out double sided, and put it in a 3" 3-ring binder with heavy weight plastic page protectors. We added a bit of flair to it with our vinyl cutter and printed a little ATARI logo for it while we were at it. The book mentions the STELLA PROGRAMMER'S GUIDE, so I also printed a copy of that and put it in a smaller 3-ring binder to have it as a reference.

I am happy with the results.
