Driver for the original (SCSI)CanoScan 2700F. Driver version v3.6.6 (and twain). It needs the latest Adaptec WinASPI v4.71.2 layer installed first for the scanner to be recognised on your system. Then install the software followed by the scanner. I have run it with an Adaptec 2904 SCSI card for which no drivers are needed. May also work with Windows ME.
