You need a cable which connects the CD32 aux / keyboard port to the serial port of the 1200. You then run the software off cd and there was also a floppy disk.
The cable can be made up easily and if you should also be able to find the .adf of the floppy.
Sorry to be vague, if I was using a proper computer right now (on a Kindle), I'd be able to do some searches for links more easily.
