This is similar to an earlier post. If you have the A1200 towered up and you have a zorro IV backplane, then the cheapest and most effcetive way to go is to buy one of the DCE CV64/3d which work at all double speed to normal zorro2. When people talk about the a4000 as a better option this only applies if you can get an upgraded A4000 cheaply. A stock A4000 (even with a graphics card and the stock Commodore 040) will be slower than your towered A1200 system with a graphics card. you probably have got a keyboard adaptor and an IDE splitter already and A1200 accelerators are cheaper and easier to get than for the A4000
