QDOS 0.10

QDOS 0.10 was the first release of 86-DOS to exist. This version was about the half completed version of the operating system. In an addition to the earlier 8-bit FAT file system, this version already had supported 12-bit, and the number of FATs had fallen to 2 from 3. This version would have another edition, QDOS 0.11. This version used 16-byte directory enteries so QDOS 0.10 isn't compatible with what was going to become FAT12.
