http://www.amiga-hardware.com/blizz1230iii.htmlThe last picture shows the SCSI-module of the 1230-III. If you don't have it, you could try scanning some amiga auction sites or ebay for one. Good luck with it though, I haven't seen them around much.
1230-IV/1260 scsi modules were much more common, but are not compatible with 1230-III.
