I'm not overly experienced with this, so I could be wrong, however I once had a CD32 and had it set up the way your looking to set yous up. I believe the only way to do this is to purchase the SX1 addon for the CD32. This basically allows you to turn your CD32 into an A1200. As I said, I had mine set up this way years ago, and I am not aware of any other way of doing it.
