WinHelp to HtmlHelp conversion, part 1 The original version of CiderPress used a WinHelp help file, built with an application called HelpMatic Pro. This app used a proprietary format, and had no facility for exporting to "raw" HPJ + RTF files, so I decompiled the HLP and imported it into HelpScribble. Using HelpScribble, I cleaned up the help file formatting a little, fixed up the table of contents, and exported as "raw" HtmlHelp (HHP, HHK, HHC, and a whole bunch of HTML). I also split the pop-up help text, which isn't supported by HelpScribble, into a separate text file that Microsoft's HTML Help Workshop understands. I'm checking in the files that HTML Help Workshop needs to generate a CHM, so anyone can update the help text. I'm also checking in the CHM file, rather than adding the help workshop to the build, so that it's not necessary to download and configure the help workshop to build CiderPress. This change adds all of the updated help, but only updates the Help and question mark button actions for one specific dialog. A subsequent change will update the rest of the dialogs. This change is essentially upgrading us from a totally obsolete help system to a nearly-obsolete help system, but the systems are similar enough to make this a useful half-step on the way to something else. The code will centralize help activation in a pair of functions in the main app class, so any future improvements should be more limited in scope. This also adds a build step to copy the CHM to the execution directory.

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">The DOS 3.3 file format is wonderful for 140K 5.25" floppies, but requires some modifications before it will work on other kinds of media.&nbsp; A number of authors came up with ways of putting one or more DOS 3.3 volumes onto an 800K floppy.&nbsp; CiderPress recognizes most of them automatically.</FONT></P>

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">Apple shipped two 3.5" drives, the AppleDisk 3.5 and the UniDisk 3.5.&nbsp; The latter, combined with an interface card, would work on an Apple //e, and is responsible for the suffix used in some of the product names.</FONT></P>

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">ProSel-8 and -16 shipped with Uni-DOS, a way to format an 800K disk with 600K of space for ProDOS and 200K of space for DOS 3.3.&nbsp; The embedded volume had 50 16-sector tracks.</FONT></P>

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">Essentially an enhanced version of Uni-DOS, DOS Master allowed placement of multiple DOS volumes on a single disk.&nbsp; You could, for example, put five 140K DOS 3.3 disks on one 800K disk, and switch between them with the ",v" (volume) parameter.&nbsp; The volumes could also be placed on a hard drive.</FONT></P>

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">The "Amateur Disk Operating System version 3.5" software allowed storing two 400K DOS volumes on one 800K floppy.&nbsp; Each DOS volume used 50 tracks of 32 sectors, which is the largest you can get without making significant alterations to DOS.&nbsp; The change from 16 to 32 sectors broke compatibility with some programs (such as the "FID" file copying utility), but was manageable with a few well-placed patches.</FONT></P>

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">This is another two-400K-disks-on-one-800K scheme, but the author decided to do something a little different.&nbsp; Instead of putting the volumes one after the other, he stretched them out across the entire disk, using odd sectors for one volume and even sectors for the other.&nbsp; For a device that reads 512-byte blocks, this makes a certain kind of sense.</FONT></P>
