Intecolor 3621 ad from 1979
The big selling point for Intelligent Systems’ computers was their high quality color graphics.
From the advertisement: Our new Intecolor 3621 puts the color advantage in a desk-top computer. The 13-inch screen can display 32 lines of 64 ASCII characters, as well as plot graphics on a 128 x 128 grid—in eight brilliant colors.
