Ultimeth Software

Dean Gibson from Ultimeth Software granted permission to post the software and manuals:

"Permission granted! Sincerely, Dean Gibson"

Ultimeth Software provided drivers for several different hardware items:

  • HDOS Hard-sectored driver supporting double-sided, 80-track floppy drives
  • HDOS MMS Soft-sector controller

I'm sure there were many more, but

The company is still in existence, see what they are up to on the Ultimeth Systems website.
