Phase 5 – Cybervision 64/3D RTG


I recently picked up this RTG video card for my Amiga 2000 system. This makes a wonderful improvement to the A2000 video output. While surfing the internet, the webpages are displayed in their full color pallet. The only issue I have is that this card doesn’t support mode promotion. What that means is if you want to run a piece of software, such as demos, games and some applications that use the native amiga display modes, you new RTG graphics screen goes blank. That’s because the Amiga is displaying it from the Amiga video out. SO, to remedy this issue, you have to buy a VGA switch box. This will allow you to switch video out ports using a single monitor. If you aren’t running a scan-doubler, you would have to find a monitor that will sync to both 15khz and 31 khz. With a flickerfixer, such as the AGA-2000, A2320 or RGB2HDMI, installed in the video slot or an Indivision ECS that shouldn’t be an issue.

This card, when installed in an A2000 must be inserted into the into the number 1 slot. It will not work in any other slot. I discovered this the hard way. The seller didn’t include the manual. After about an hour of frustration, I finally downloaded the manual and voila, there it was! “Install in Slot 1”. When all else fails…read the manual.

Here is some additional information on the video card from the Big Book of Amiga Hardware:

The Cybergraphics 64/3D is a Zorro II and III auto-sensing graphics card. It has a pixel clock of 135Mhz (8bit), 80Mhz (16bit) and 50Mhz (32bit). It has hardware handling of complex 3D operations, hardware overlaying and DPMS power-saving. A companion scan-doubler card was also made for this graphics card which is designed to fit AGA-style video slots.

A monitor switcher and MPEG Card were also planned, although the MPEG card was made, it was never released to the public. The scan-doubler does not work fully in non-AGA systems, the native display is not scan-doubled but is simply passed through.

Apparently there are modules which can be used directly with the Virge DX chipset and should in theory work with the CV64/3D however drivers would be a problem.

The only real difference between the original Phase 5 version of this card and the DCE Mk-II version is that the latter supports the “Fast Mode” for Zorro II found on some A1200 bus-boards.
