OS/2 2.00 build 6.605

OS/2 2.00 build 6.605 is a beta build of OS/2 2.0 from September 1991. Michal Necasek, author of the OS/2 Museum blog, has this build, but then stated that the disks were not owned by him, and the owner told him that he was not allowed to share the disk images. The reason for its out of sequence build number remains unknown.
