  I've got an old 5 1/4"  13MB (10MB) Hard disk drive, taken from an old
Sharp MZ5600-A. Does anyone know whether or not it is possible for this
drive to be used in the Archimedes - I have a SCSI i/f and the ST506 i/f.
The Drive has a make code DK503.

  Secondly, what drives can I use with the Archimedes. When looking down
lists of Hard disks in the PCW, you generally see ST numbers, and possibly
type of drive such as RLL,SCSI,IDE, etc, how do I know which will work with
the Archimedes - I've only seen one ST506 !

  That leads onto my final question about Hard Disks, what makes an RLL drive
different from a SCSI drive - in terms of internal Hardware ? I have previously
assumed that the RLL has an interface which compresses the data going to the
disk, and this i/f sits as a front end to the standard drive i/f which 
actually does the controlling of the heads.
