The SCSIDirect SHOULD work on all SCSI controllers but it DOES NOT! This is
the main reason that my SCSI utilities still are beta versions and I could
not send them to comp.binaries.amiga yet. The most trouble causes the A2090
which works not always. Mostly it hangs after a few SCSI commands and it
always reports ILLEGAL OR UNEXPECTED SCSI PHASE errors.
Also the GVP Controllers doesn't make the life of a SCSI tool programmer
very easy. They use two total incompatible devices with the same version
number! One supports the SCSIDirect and the other does not.
The SCSIDirect works great with Amiga 3000, A2091, HardFrame and the GVP
device for removable media. It also works with the FireBall from M.A.S.T.
(I could only once test SCSIinfo on it). About the other controllers I
can't tell beacause they are not available or not popular here in
Swizterland.
