That may be simplier, but probably will still require some work. I was
searching for some more information on SASI drives and came across a
couple of pages that stated or implied a conversion may be needed. On
this page they describe their SASI or SCSI 1 to SCSI adapter:
On this other page, it shows that of the drives that are available,
only one states that it's compatible with SASI. Two other ones state
"We support the drive in SCSI-2 systems and in some SASI systems." The
others ones state "installable only in SCSI-2 systems. Operation in
SASI systems is not supported."
Here it states: "Part of the original SCSI interface was based on
SASI. However, second generation SCSI eliminated most of the SASI
In addition to finding the right drive, you will also have to build
the cable since it's not the same pin-out (or even number of pins).
