IBM PC-DOS 6.10 (6-29-1993) ("IBM DOS Version 6.10")
Released in 1993 by IBM
For IBM compatible computers
Image quality: Used
Note: This version is branded as "IBM DOS" in the software although
it says "PC-DOS" on the disks. This version does not include drive
compression. I recall these disks were bundled with an IBM branded
computer.
This disk compression software, reportedly, was released shortly
after the initial release of 6.1, so earlier 6.1 versions lacked it.
IBM also went back and forth with the "IBM DOS" vs "PC-DOS" branding.
