The 360 interface is by current standards a moderate performance channel
interface in the same ballpark as SCSI-1, only somewhat more complex and
with great big connectors about the size of a tennis ball. The main
advantage it has over SCSI is that the lines can be many feet long, which
was important back when a 20MB disk was the size of a washing machine.
These days I'd think that de-facto and de-jure standards like SCSI and IPI
and the various backplanes like VME and even EISA make the old 360
interface pretty uninteresting.
