The Picasso II is a Zorro II only graphics card. It has a pixel clock of 85Mhz (8bit), 45Mhz (16bit), 28Mhz (24bit). The Picasso II requires Workbench 2.0 or above, and includes two connectors, one which is designed to pass through native Amiga video, and one for the physical attachment of the monitor. Depending on the cable you have the Amiga's native video can either come directly from the the RGB port, or from another flicker fixer or scandoubler. For A2000 owners, the Picasso II also supports segmented memory. This means that the graphics card can still be used, even if you currently have other peripherals (such as memory) which are using up the full Zorro II address space. However in segmented memory mode, performance is degraded and applications may not behave very well. Please also note, that depending on the RTG driver you use (P96, CGX, EGS), segmented mode may not be supported. To change to segmented memory mode, there is a jumper next to a row of four chips, on the right hand side of the card. This should be ON to enable segmented memory.
