ummm, just had an idea come to me …. on the super os/9 disk, when running in the os/9 environment, there are two programs in the cmds folder called cbmwrite and cbmread. I used cdmwrite to write the 0s9.d8d9 module file out onto the native part of the CBM disk which can be read on the  superpet using the waterloo micro editor.

I bet cbmread does the opposite …. will try it to see if i can write the files out of the os/9 environment and then use cbmread to put them back in having copied them onto an 8050 format disk - all in vice.
