If u can't get scsi then another option is to get one of the ata (IDE) zorro boards eg fastATA 4000. big hard drives are cheaper as IDE rather than SCSI and also alot easier to get, as are cdroms and cd burners and the filesystem even allows you to use dvd drives and read dvd's (but not burn dvd). apparanlty it is possible to get 14 meg/sec. u should get OS3.9 with the updates though, and i have heard something not being quite right when a big (40-80 gigabytes) hard drive is partitioned with >4 gig partitions. anyone know more about this last thing?
