I've had no problems with mine and would recommend it to anyone with an old
HD20 who doesn't want to buy a new SCSI disk.  It comes with a board and
a new cable.  The new cable is a DB-25 plugged directly into the Mac port.
The board provides a second DB-25 connector for expansion.  The DiskTimer II
results are:

          Write     Read     Seek
HD20      1479      1304     60
HD20WSI    136       134     48
HD20SC     162       160     38

So in all but Seek time, it is even faster than the standard Apple SCSI
drive.

                                                        Jeff
