If you can't find any images then you can use Kryoflux free on your A1200 to make your own. You wont be able to write them back to disk but you can send the images to the SPS team who will make SPS images of them for you.
You will definitely need a CF card in CF0: for the backup though.
Failing that, there is a good ADF copy on The Games Archive site.
