The problem with TWAIN, as I recall, is that it wasn't actually
a standard API between devices and OS so much as a standard way
for an application to call a manufacturer-supplied application 
in order to control and receive images.

That's why it was completely supplanted by SANE, which more or
less standardizes the device-OS interface as well as the
application-application interface.

You might manage to get the Windows TWAIN software to run in
WINE, or if you have a Windows 95/98 virtual machine, that would
probably work.

I would note, though, that this camera appears to have terrible
specifications by current standards:

1360x1024 at 7.5 frames/sec

640x200 at 30 frames/sec

and the SCSI connection is designated for connection to a
storage drive or printer.

If you are specifically looking for a microscope mountable
camera, there are lots of relatively cheap C-mount cameras
and C-mount adapters, all with much better specs and much
easier to access.
