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version compared to the current released version of Model I except that the Model III version added DOS8 and DOS9 (DOS9 superseded HELP/CMD).

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.
