How did the Atari 2600 achieve a resolution of 160 x 192 pixels with only 128 bytes of memory?

You don't have to store the frame "in memory" before you "serve" it to the display; you would "compute" the image as you transmit it. Here is an FPGA example: https://...

How did the Atari 2600 achieve a resolution of 160 x 192 pixels with only 128 bytes of memory?

The 2600 didn’t have a frame buffer. Instead, programs running on it had to draw the picture on the screen pretty much in real time. This actually had some advantages on a low-cost system. Each line ...
