  •  Model I/MultiDOS v1.0
  •  Model III/MultiDOS v1.0

Background:

  •  Originally called ULTRA-II an ‘internal’ DOS as the first name assigned to what became MULTIDOS. ULTRA-II was NEVER sold or given out to beta test.
  •  Was released as a “new operating system by the author of ULTRADOS” and as the only DOS that can read (copy files from) all of the Model I and Model III operating systems. At the time “all” the Model I and Model III operating systems were: TRSDOS, NeWDOS, ULTRADOS, VTOS, DOSPLUS, DBLDOS, LDOS; and MULTIDOS.
  •  Model I version had a “fatal bug” in DOS0/SYS discovered by Kim Watt.
  •  The Model III version compared to the current released version of Model I except that the Model III version added DOS8 and DOS9 (DOS9 superseded HELP/CMD).

MultiDOS v1.1

General Info:



Released:
    January 15, 1982
Versions:
     Model I (Single-Density)
Files:
     26 files, 12 of which still bear the v1.0 file date of September 1, 1981
Main Changes from v1.0:
     Fixed DOS0/SYS
     Added HELP/CMD
     Added SKIP/CMD
Beta Testers:
     Initial enhancements incorporated from feedback provided by: Johnn Audritsh, Charlie Butler, Mike Friedman, Andy Gariepy, Gordon Monnier, Kim Watt, and Paul Weiner.

     Model I/MultiDOS v1.1
(Note: Bears v1.0 Version Number)

Background:

  •  Kim Watt discovered a “fatal bug” in DOS0/SYS, and since MULTIDOS v1.0 did not have a ZAP utility, Vernon had to send all his customers (about 10 at the time) a new diskette. Vernon did not advance the version number (so it still reads v1.0).
  •  What was the bug? Well, there are five ways to interface to a dual-sided disk drive: [1] treat it as a two drives, [2] treat it as an 80 track drive. i.e., if the cylinder is above 39, subtract 40 and select side 1 (this is the way MAXIDOS interfaced with dual-sided drives), [3] treat it as a two-volume diskette (original way DOSPLUS interfaced to dual-sided drives). MULTIDOS/ESOTERIC still supports this scheme, [4] treat it as a one-volume diskette (original way LDOS interfaced to dual-sided drives). MULTIDOS/ESOTERIC supports this scheme, and [5] treat it as a one-volume with overflow.
  •  The intent was to initially write to side zero and use side one only if side zero is full. This is the way DOS0/SYS was designed (incomplete at the time Vernon had to ship product). Vernon thought he had sufficiently ‘JRed’ around the ‘overflow code’ before Vernon shipped any – but he didn’t. Subsequently, Vernon abandoned the ‘overflow’ concept.
