Atariage user Ramses let us know about this video of the Atari programmers panel from the Portland Expo 2015. It includes Bob Smith, Tod Frye, Rob Zdybel, and Howard Scott Warshaw. Anyone interested in retro game development should watch it. Really interesting.

On a side note, the video and sound are perfect, which is very rare in retro events unfortunatelly.
