Many of us first learned about computer graphics on our TRS-80s. We had 64x16 characters mixed with 128x48 pixels! But where did this capability come from? As it turns out, the TRS-80 graphics design probably drew inspiration from a few earlier, lesser-known machines. This presentation traces the history of the TRS-80 graphics, through the influences of earlier machines such as the TV Typewriter I, the Sol-20, and the Poly-88, all of which set the stage for the TRS-80 Model I.
