Great news! I recently interviewed Wes Newell, founder of Newell Industries (known for Omnimon and many other upgrades.) (The interview is not published yet.) He sent me hundreds of pages of documentation and source code to scan, and put online. And he's put it in the public domain!*
So, I've scanned it all and uploaded it all to the Internet Archive. The manuals are pretty straightforward, seems to be rather complete set of Newell manuals. I need your help to identify and describe a lot of the source code. With more information about exactly what this stuff is, I can amend the metadata at archive.org.
I think the Atari community will find some of this source code very exciting. So dig in and tell me what we've got.
(*I'm not entirely convinced that the Omnimon/Omniview manuals are his to put in the public domain — they may be owned by David Young of CDY Consulting) so I didn't tag that PD in the uploads.)
