They do not support INQUIRY, for example.

INQUIRY is, even by the old SCSI standard, "required for SCSI devices
that support device-independent self-configuring software", so the
host adapter software (i.e. driver) can determine the type of SCSI
target connected. It's mandatory for SCSI-2.

So if you want some SCSI host adapter software that is clever
enough to handle streamers, CD-ROMs, printers, scanners, etc.
correctly, then better forget about the ACB-4000.
