BTW - if you really do want to do it the hard way, I believe you can get to the mini assembler by 1) loading integer basic (from a DOS 3.3. master disk) 2) call -151 (to get into monitor) 3) F666G (to jmp to mini assembler) Instructions for using the mini assembler are on the apple support website (!?!!) http://support.apple.com/kb/TA40023 Regards jonno
