These all work correctly on any PC Card machine. The only reason they came in this way was because these devices were original marketed only in Japan. I've used all these cards with external SCSI drives in the past. As far as I know, only the if_snc driver, which was removed, is truly pc98 specific. It is wired in such a way that cannot be used in ibm-at compatible laptops. IIRC, it had hard-wired memory decode lines that landed in the middle of the VGA graphics pages or BIOS low memory areas. I have one of these cards still, and it will be detected on my laptops, but can't work due to the required mappings. Now, there's an different question about whether it is time to retire some of the now-ancient SCSI cards from the system, but that's a different kettle of fish that's larger than just nsp, ncv and stg.
