    Hello again,

    The Power Macintosh 7200 models had a SCSI hard drive, and they were equipped with an external SCSI port. So, you could connect a SCSI hard drive from your PowerTower Pro 225 to a 7200, either internally or externally.

     

    If you wish to just replace the 7200 internal hard drive with the one from the PowerTower Pro (SCSI ID 0), you would have to use an appropriate system CD or floppy disk as a startup disc/disk, unless the PowerTower Pro hard drive contains a universal operating system version that works with the 7200.

     

    Otherwise, you could add the PowerTower Pro hard drive to the SCSI chain (internally or externally). If so, the SCSI ID of that hard drive must be changed to a suitable value. A purely external solution would require a powered enclosure with an ID switch, but at least a temporary setup internally should not be too difficult to arrange (ID change via jumpers).
