Stop and think.

A disk drive marked RF/RZ35 means that the head-disk assembly is common
to both RF35 and RZ35 drives.  But the electronics is different.  RF is
DSSI, RZ is SCSI.  The quick-look clue is that DSSI drives have 5-pin
power connectors, SCSI have 4-pin.

What you have is a box full of DSSI drives, and they won't work on a SCSI
bus, even if you can find a signal cable adapter.
