  You should look at article <1990Dec30.091947.928@spcvxb.spc.edu>, where I

  in reference to the 6-button front panel upgrade. That article contains
other important information on this subject, and I suggest you read it.

  As fat as "jumpers on the disk drive" go, the RD5x are (at least as far
as this subject is concerned) industry-standard 5.25" drives. There are no
jumpers for ready/write protect on the drive itself. The front panel gener-
ates those signals and passes them on to the RQDXn controller.
