October 16, 2010 – More Model I MultiDOS Images Vernon Hester has kindly provided Model I MultiDOS versions 1.0, 1.5S, 1.5D, and 1.5P. Enjoy.

October 12, 2010 – MultiDOS Update The existing copies of MultiDOS for the Model I have been reviewed by Vernon Hester who has explained some of the images, and provided information necessary to restore others to verified true copies. If you downloaded the Model I MultiDOS images in the past, you might want to re-download them. Interesting Notes:   •   MultiDOS for the Model I came in three formats: Single-Density, Double-Density (similar to DOSPLUS and LDOS), and “P”-Density (similar to NEWDOS/80 Double-Density which has track 0 as single density, and all other tracks as double density).   •   MultiDOS v1.5SK (at least my copy) was really just a special kernel made for Computer Shack so they could distribute SuperDirectory (since a disk cataloging program needs to be able to read as many DOS’s as possible; which is MultiDOS’s specialty). That is why the system files are all called CSx/sys (Computer Shack) and the version is SK (Special Kernel)! It has only 16 Library commands: Auto, Boot, Clear, Clock, Cls, Config, Date, Dir, Forms, Kill, Lib, List, Print, Skip, Time, Verify.   •   MultiDOS II (at least my copy) was really just a distribution diskette for ZEUS. This DOS will boot on a Model I and a Model III.   •   While most of my MultiDOS images were modified to some level, the copies of v1.4S, 1.4D, 1.6D, 1.6S, 1.7D, and 1.7P are all now “correct.” Vernon *may* be providing “correct” copies of v1.0 and v1.5 in the future. Of course, Vernon has provided 2004 and 2005 updates to MultiDOS, but for those who want the classic versions, there you go.
