Is there some "DB25-to-50pin"-adapter-cable or something, or do I need a casing for the CD with a 50-pin port on the inside and a DB-25-port on the outside?
;-) Yep! A 50-pin to 25-pin SCSI cable is the thing to use. These can often be found in your charity thrift stores, or you can try a Macintosh retailer. They may have some in old stock, since the earlier Macs used SCSI as standard.
