Hence it is normal that a disk initialized in ProDOS is not suitable for being catalog listed from a DOS 3.3 flavour of Merlin... Therefore I would suggest that: a) you exit from Merlin main menu (Q command), b) eject the disk in drive 1 of your emulator box and do a file copy under Mac OS X of this disk image file. c) insert the copy in drive 2 of your emulator box d) Type the command "INIT HELLO,D1" from the "]" command prompt. e) Place the newly inited disk image into drive 2 of your emulator box f) Reboot the Merlin disk (after inserting its disk image into drive 1). g) From Merlin main menu, you should then be able to catalog the disk in drive 2 of your emulator box (just select drive 2, beforewards). From then on, copying some source files from disk 1 to disk 2 under merlin should be easy, do not forget to Save .s files and to Write t. text files for such copying in order to preserve the usage of such files. -- Growing old is mandatory.. growing up is optional.. But the other way round is as true.
