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.

August 3, 2010 – New Downloads (Scott Adams)
Vernon Hester’s downloads are live (so when doing an archive search you will get hotlinks with the findings). Since Scott Adams had long ago (and also today) allowed me to post his adventures, those links will go live tonight as well. If I can think of other authors who have authorized release, I will move those files over as well.

Vernon B. Hester, author of MultiDOS and other wonderful programs, has made his software and manuals available:

Astrocal Manual (5th Edition) – DOC Format
Astrocal Manual (5th Edition) – PDF Format
MultiDOS Manual – DOC Format
MultiDOS Manual – PDF Format
Zeus (9th Edition) – DOC Format
Zeus (9th Edition) – PDF Format

When my host fixes my SQL upload, and I can get into the TRS-80 Archive Lookup, I will post the corresponding software packages here for download.

Also as previously noted, Vernon has a blown Model 4 power supply, which is preventing him from providing updated software. Any help is appreciated.

July 31, 2010 – Need Model 4 Power Supply
Vernon Hester, who wrote MultiDOS and a few other programs, had been updating his programs and DOSes. Vernon was in the process of updating a few more items, and getting together a real copy of the last Model I single density MultiDOS, when his Model 4 power supply went out. Does anyone out there have a source for a Model 4 power supply for Vernon? Thanks
