Hi Thanks again for all the help and encouragement my AIM65 lives. The last H/W problem was serial comm between my Mac and the AIM 65. Mike Stein devoted quite a bit of time and email helping me to get it working. Now I can transfer data between the AIM 65 and the Mac. Now all I need is a way to convert cc65 object files into Mos Technology Paper Tape Format text files so I can transfer programs assembled/compiled on the Mac to the AIM and use the Mac to store data from the AIM in paper tape format text files. I have been asking around but I can't find anyone who has written a converter to convert from cc65 object file format to paper tape format text files. Anybody here ever done such or have any info which might help me do it myself? Any help much appreciated, Andy
