SCSI cable

I bought an external SCSI ZIP drive through Ebay, but I still need the right cable to save/load from my MPC 2000XL (only the 25 to 25 pin cable came with it). I know I need a male 25 pin to male 50 pin micro SCSI2 cable. Only they got two types of 50 pin male connections: CN50 and IDC50...

Am I right to order the IDC50 ?

No - you want the HD50 Male to plug into your XL and a DB25 male to plug into your zip.
