A Zorro III only graphics card which has 4MB of 20ns VRAM. It has a pixel clock of 110Mhz, or 170Mhz for versions containing the Inmos G365 chipset. Screenmodes can be user-defined for this card using CGXMode but apparently for the default installation of screenmodes, the only one which works is 768x576 due to syncing problems of the Inmos Chip. A reset may be needed before chaning screenmodes. If you intend to use this card with Shapeshifter then it will only work in 8bit modes as the 16 and 24bit modes of this card are not Mac compatible. This card has been reported not to work correctly if you are using an 060 and have the Phase 5 060 libraries installed. If you replace these libraries with the MMULib libraries from Aminet then the card works OK. The problems seems to be with the address space. The card announces itself as 32MB when it should be 4MB.
