Im rather new to the SCSI world, so please excuse my lack of familiarity with SCSI terminology. I'm about to embark on interfacing a SCSI based data acquisition system to a NeXT. Im sure I am in for all sorts of thrills and spills, but one application I have requires spooling data continiously from the acquisition unit to the computer and storing in on disk. Is it possible given the nature of SCSI to have the acquisition unit write directly to the disk drive (also SCSI and on the same cable) bypassing the host computer. I'm aware that I will have to perform all sorts of minor tricks, ie. prepare a special partition on the disk to allow easily transfer of contiguous blocks of data as well as getting down and dirty with commands given to the devices involved. I'm interested in minimizing delays by not bothering to store the data in the host system, only to have to write it out again. Thanks for any help, suggestions or psychiatric advice. -------------------------------------------------------------------------- Jerry S.
