You really should add a SCSI interface card. A 2091 with at least 6.6 ROMs (7.0 is better) is an OK choice. That way you can use a real SCSI drive, and add a CD-ROM in the case. If you add a CD writer then you can move files both ways, but even with a simple reader, you can get files from your PC (assuming it has a CD writer) to your Amiga with ease.
