My research showed that the original HSP editor was Howard Kaikow, which is why he was able to offer copies years later.

But maybe an alternate route might work? Surely someone must still have the full text. Okay, so thereвЂ™s no way to get the HSP through the front door. I would love to get a copy (it should contain several related articles) but I just canвЂ™t find any. The book is long out of print and not available used. The full text of the HSP was almost certainly published in the 1986 book CD-ROM Standards: The Book by Julie Schwerin, ISBN 0904933547. The High Sierra Working Paper (the actual title of the proposal) used to be available from NISO (National Information Standards Organization) in the late 1980s, but once ISO 9660 was approved, official standards bodies had no reason to distribute the obsolete proposal.ДЇor the few people who needed the original text, the High Sierra proposal used to be available from Howard Kaikow, but he passed away in 2011.

IBM Warp 4 CD-ROM from 1996), but no one really noticed because everything worked just fine. Sometimes CD-ROM publishers used HSF well into the 1990s for no apparent reason (e.g. That in turn meant that CD-ROM file system implementors were forced to support HSF for many years to come, otherwise users would rightfully complain that CD-ROMs that can be read just fine in DOS arenвЂ™t recognized. Since ISO 9660 isnвЂ™t really any more capable than the original HSF, publishers had very little incentive to use ISO 9660 and a lot of good reasons to stick with HSF.ДЄs a case in point, MicrosoftвЂ™s C 6.0 (May 1990) or ProgrammerвЂ™s Library 1.4 (June 1991) CD-ROMs used the High Sierra format, not ISO 9660.

The same problem was presumably present on the mastering side: Existing CD-ROM publishers had software which supported only the High Sierra format and since it worked just fine, they werenвЂ™t motivated to spend money (probably quite a lot of it) on upgrades. MSCDEX 2.0 was not a free upgrade, which is why until about 1990, CD-ROMs in ISO 9660 format were exceedingly rare. MSCDEX shipped with CD-ROM drives, and existing CD-ROM drive owners had MSCDEX 1.x which only supported the High Sierra format (HSF). In addition, it wasnвЂ™t about until July 1988 that MSCDEX 2.0 with ISO 9660 support started shipping, which means that until then CD-ROMs in ISO 9660 format would have been unusable in practice. But even that was enough to show that although the structure defined in the High Sierra format is not far from the ISO 9660 standard, the two data structures are just different enough to be mutually incompatible.Д®ven though the High Sierra Proposal is long obsolete, and it never even was an official standard, it was the de facto standard from mid-1986 until ISO 9660 was approved. Said article recaps the HSP in very good detail but itвЂ™s not the actual text.

The closest thing I could find was an article in the excellent PC Tech Journal in the July 1987 issue ( Patterning CD-ROM by Peter Jansson, page 163 ). I found a number of articles talking about the High Sierra Proposal (HSP) but not the actual HSP text. proposed standard) turned out to be rather unexpectedly difficult. The other part of my motivation was the usual insatiable curiosity.ДЇinding the actual text of the High Sierra Working Paper (also High Sierra Proposal, i.e.

This was in part spurred by the fact that I have a number of CD-ROMs/images that use the High Sierra format (Microsoft ProgrammerвЂ™s Library, some IBM Developer Connection issues, OS/2 Warp 4, and more) that both macOS and Windows 10 refuse to mount. Some time ago, I thought it would be useful to understand exactly what is the difference between CD-ROMs recorded in the old High Sierra format versus the ISO 9660 standard.
