These are the files on the original installation disk (version 1.25) for the Imation LS-120 SuperDisk external parallel port drive. They're for Dos 6.X, Win 3.X, Win NT, Win 95 and Win 98. Might work for Win ME too.
The zip file will extract to a folder named 'LS-120_Parallel_Port'. You can run setup from there or copy the files to a floppy disk.
I added a jpg of the actual disk label. There was an Msdos.sys file for Win 95 on there that I deleted because I didn't think it was originally included and was concerned it might overwrite your version. If for some reason you get an error about it missing then report back and I'll upload a version including that file.
Be sure to read the readme.txt file as it has info about renaming a file prior to installation.
