Is it like a F30? I have a RS/6000 running AIX with a DDS2 DAT tape and CD-ROM drive running right behind me. It has a 3 1/2" floppy mounted on edge in the right most position, a SCSI CD-ROM drive mounted on edge next to the floppy, a DDS2 DAT tape drive and then an empty position. I'll attempt to find the manual. Thanks Mike
