86-DOS 0.33

86-DOS 0.33 was an unreleased beta build of QDOS/86-DOS. The only specific information known about this build is the lack of variable sector record sizes, later added in 1.00. However, as version 0.34 didn't change any features from 0.33, it is safe to assume that all features from the 0.34 manuals are present in this version as well.

Barry Watzman disk
comp.os.cpm newgroup member Barry Watzman (May 26, 1949 – May 17, 2010) owned and subsequently sold five Seattle Computer Products floppy disks, including an 86-DOS 0.33 disk. Watzman bought the 8-inch diskette directly from Seattle Computer products due to an ad in BYTE magazine. Along with the operating system and them manuals that came with it, he also bought SCP's S-100 system, including the hardware used inside the Gazelle and the Tarbell double-density disk controller.
