Certainly not all.  I worked on trying to port some NEFF data acquisition hardware designed for VAX into a Windows environment, at first using Adaptec Narrow SCSI interface cards with the Windows DDK and it was impossible.  We ended up having to use a another piece of COTS differential DIO hardware to interface with the unit.
