SASI uses one less wire than SCSI; if you make sure that this wire (/ATN, pin 17 on the Macintosh DB-25) is not kept grounded by your SASI box, then it should be possible to use nonstandard SCSI drivers (of which several are floating around) to read/write to your SASI controller. The command set, however, of SCSI is well established; SASI is likely to be missing some part of the 'common command set', and you will need to know how to write a driver that works around this problem. I don't know of anyone who's actually done this, but the subject does come up from time to time. John Whitmore
