Has no one ever heard of APE?
Yes, I used there stuff some time ago. They sell ( or you can roll your
own ) an interface cable that goes between an ATARI disk drive and your PC.
All I can say is it does work. Their software also lets you connect an ATARI
computer to your PC but I think the interface cable is slightly modified. At
least this way you can get your code into your PC using an ATARI drive. Good
luck !
