You may want to get some kind of removable media for your Amiga, many people use a compact flash card as a hard drive, then use an IDE to CF adapter [1] to attach it to an A600/A1200/A4000. You can format the CF card as a standard Amiga hard drive, then you can remove it and read the Amiga drive on a more modern computer with unadf [2] and you can convert your AMOS source code to readable text with listamos [3]
