Tried to salvage a file from a friend's floppy dated all the way back to 2003. Scandisk, chkdsk, NDD all failed, only Diskfix from PC Tools partially made the disc readable (barely).

What CPU do you have? These memory Managers require a 386 At least. Or do you have a EMS card?

There is a card specific driver that should be still available, compare here: EIZO MD-B12 TIGA TMS34010 This driver is also needed as basis for the Windows driver.
