For users of NuBus Macintoshes, the ProLegendGA is the right choice. A special graphic chip, developed by Formac, it allows a very high acceleration of the screen redraw. 3MB of VRAM and the additional 1MB onboard DRAM for font-, pict cache and G-World support give an additional performance enhancement. The ProLegendGA is compatible with all standard monitors and allows a resolution of up to 1152 x 870 pixels with 24 bit colour depth and 75Hz.
