Radius Displays, Video Cards, and Clones

Radius was founded in May 1986 by Burrell Smith, Andy Hertzfeld, and other members of the original Mac team. Radius produced the first full-page display for the Macintosh, introducing the Radius Full Page Display for the Mac Plus.

Umax SuperMac Clones

Umax acquired the Macintosh clone operation and SuperMac name from Radius, going on to become one of the more innovative clone makers. Their corporate goal was to make quality Mac OS computers at prices that would give PCs a run for their money, something I believe they succeeded at.
