Yup. > * How many heads, cylinders and sectors does it have? 8 heads, 1024 cylinders, 17 sectors > * Which jumpers are used to select the unit address? Usually labeled "1" through "4". DEC standard is "3". For a PC you want "2" if your cable has a twist in it, or "1" otherwise. > * Any other jumpers need to be changed?
