I said this about the A3000 because the A2320 circuitry is built-in to the A3000. Both the A2320 and the built-in display enhancer on the A3000 can work with the productivity in that the display enchancer gets out of the way of the custom chip set that produces this ECS modes. I would recommend that if you have an A3000 or an A2000 with the A2320 card installed that you always use the hi-res (non-ECS modes) modes for better system throughput rather than the ECS video mode called `productivity mode'. Also, the A2320 works in all A2000 machines that have the two 36-pin connectors of the video slot. What I was refering earlier to was those German A2000 motherboard that only have one 36-pin connector which is only half of what we all know and love called the video slot. You can determine if you have one of the very early German designs by looking at your video slot. If only one 36-pin connector, then you have the early machine and you cannot use the A2320. If two 36-pin connectors in line with each other are on your A2000, then you can use the A2320 in your system!.
