   The book "Racing the Beam: The Atari Video Computer System" is a pretty interesting overview of the technical challenges they had to overcome. The racing part comes to having to have the frame ready to paint before the CRT beam drew them.

   Racing the Beam: The Atari Video Computer System

   Is a good read about the Atari 2600 and how the devs were able to fight within the limitations of 1970s and 1980s hardware to develop a gaming platform.

   128 bytes and no framebuffer.

   They had to "race the beam" ... but the VCS was not as fast as the beam, which is why Atari 2600 games always have a horizontally stretched look to them:

   https://en.wikipedia.org/wiki/Racing_the_Beam

   "The book's title comes from the fact that the Atari 2600, initially branded the VCS (Video Computer System), did not have a video frame buffer, and required the programmers to write each line of video to the television, one line at a time. As there were only a limited number of machine cycles in which to do this, the programmers were literally racing a high speed electron beam across the screen."

   "By paring back the hardware, the designers of the Atari Video Computer System gave game programmers room to be creative"

   That's some rose-coloured glasses right there if there ever were any.

   "You know, we COULD give this thing hardware sprites, independent video and audio chips!" "No! Think of the game programmers! They thrive on constraint!"

   My money is on the money.. The cheapest design that still allowed (the best programmers to make) reasonably good games.

   That said, the system was enjoyable to play when I was a kid, and it's enjoyable to read about now, great article!

   Here's a description from wikipedia:

   The book's title comes from the fact that the Atari 2600, initially branded the VCS (Video Computer System), did not have a video frame buffer, and required the programmers to write each line of video to the television, one line at a time. As there were only a limited number of machine cycles in which to do this, the programmers were literally racing a high speed electron beam across the screen.[1]

   I read about it somewhere else too, but it's late and I can't remember where. Will update tomorrow if it comes to me.
