I did'nt try it under win98 and my DAT is SCSI, but it should work with parallel interface. This version is old one -v1.0- and I don't success to find a recent. It will install drivers and program all together. I know there is the version 1.7 wiht possible upgrade on cnet.com - "ob800.exe" for colorado backup. If someone have this version, thank's to send me!
