Microcode on Floppy for MV-2000dc Mod II

Hello, We have a MV-2000 Mod II that we still use to manage our business. As time goes by, more and more of our tapes (DC-1000 21mb cartridges) are failing. I do have a copy of microcode (ver 10) from tape that has been saved to a hard drive as a disk image. As tapes fail, I've been able to make "new" copies, but I'm running out of tape cartridges. Would anyone know where I could find microcode for our MV-2000 mod II on 5.25 floppies? Our MV has an internal 5.25 (720kb) diskette dive that could load microcode at boot time. I've already tried copying the tape image to floppy, but it appears not to be enough. I'm guessing DG organized microcode on floppy a little differently then on tape. Does anyone have any ideas?? Thanks for your time. Tom jtpinch-treiff at usa.net
