Your information is very out of date.
In 2020, me and other members of the GearSpace.com forum found several wnaspi32.dll files that are completely workable in Windows x64, even in Windows 11.
These are two files from Ratoc and one from Nexitech.
They work with all SCSI devices - scanners, samplers, CD-ROMs, hard drives, etc.
You can find and download them here:
