Fujitsu M3191F2 scanner

Hi, Just within the 10-year rule, I have a Fujitsu M3191F2 flatbed scanner. Date code on the label is 1990-08. A label on the underside refers to it as an M3191C-IS. I guess this would have been pretty expensive when new. It has a SCSI interface, resolution is 300dpi greyscale. If anyone can assist with getting it to be recognised when connected to a PC via Adaptec SCSI card, please let me know. Fujitsu were of no help, though a German user manual is available on their web site. Using the Adaptec diagnostic program, the scanner is recognised. However it is not recognised under Win 95, even after rescanning the bus. On my Amiga it is not recognised initially, but is after I rescan the bus. I'd like to find a copy of the OEM manual for this scanner. BTW, I have dumped the data from all four EPROMs in the scanner (three of which were soldered directly to the board...). -- Mark
