If that 'cheap' Drive is an SCSI Drive, just connect it to the SCSI Bus
at your ICD Hostadapter, but if that Drive is a MFM/RLL Drive, you should
get an OMTI or Adaptec 40X0 or the Controlerpart from a SH205/204 or the
Megafile 30/60, but you can't connect a MFM(ST506 Bus) to the SCSI Bus, 
you will probably damage your Drive and Hostadapter if you do it, so be
careful............
