1. What is MB Stripper
The MB Stripper is a utility program that converts MacBinary files into natural Macintosh file format.
Macintosh has a unique file system that isn't found in any other computers. It has two file streams, data fork and resource fork, and it has file creator and type information in addition. The aim of MacBinary is carrying those Macintosh specific data into other computers' general file systems, by stuffing dual-stream data into one stream. The author doesn't know further technical details or historical backgrounds. Please ask your nearest authority.
Normally, the user doesn't have to be aware of MacBinary. Although it greatly participates in computer networks in behind-the-scenes, it doesn't appear in front of the user because the networking/terminal programs or archive utilities automatically convert it when transferring Macintosh files.
Sometimes MacBinary appears, however, by some sort of wrong conversion proceduressome or in unavoidable situations. You can't use such files in Macintosh world. In that case, the MB Stripper helps you by converting the files into natural Macintosh format.
MacBinary contains extra header added by MacBinary encoder and two primary bodies, data fork and resource fork. The MB Stripper strips the unnecessary header part and extracts essential bodies. That's the reason I named it "Stripper."
2. How to use it
2.1. Drag and Drop
If you use System 7, you can use the MB Stripper by
common "Drag and Drop" operation.
Just drag and drop your MacBinary file onto the MB Stripper icon on the Finder screen. Then the MB Stripper will read the MacBinary file, create a new file according to the MacBinary header information and retrieve data and resources into the new file.
From the version 1.1, the MB Stripper allows you to drag folder. In that case, the MB Stripper checks all the files in the folder and then if there are any MacBinary files, it will try to retrieve them. It doesn'nt search , however, the folders in the folder recursively.
The MB Stripper checks the dropped file whether if it's a MacBinary beforehand. You won't get a wrongly converted file even if you drop a natural Macintosh file. (The author has tried to write the MB Stripper to do so. In case it failed, please let me know how it went wrong.)
2.2. Press "Open" button on the main window
The MB Stripper can work under System 6 although you
can't drag and drop, unfortunately.
Launch the MB Stripper by double-clicking and press "Open" button to select a file you wish to strip.
Of course this operation is available under System 7 as well. You can also select a folder using the "Select" button in the file select dialog under System 7.
2.3. Select "Open..." of the "File" menu
This operation is identical to the "Open"
You can also use "Command + O" shortcut. You can even abbreviate just pressing "O" key.
3. Are there any options
The MB Stripper offers you two kinds of option. You can let them active using dedicated check boxes.
3.1. Show File Info
If you check it, the MB Stripper will show you a dialogue box and ask you to strip it beforehand.
If you feed non-MacBinary file, the MB Stripper will show you an alert and it won't strip the file in anyway.
The default setting is on.
3.2. Trash Original (Delete Original)
If you check it, the MB Stripper will remove the MacBinary file after stripping it.
Under System 7, it doesn't delete the file but move it into trash. Under System 6, however, you'll see "Delete Original" in the check box and the MB Stripper just deletes the file.
The default setting is off.
4. On what Macintosh it works
The MB Stripper works on Macintosh Plus or greater. Required system is 6.0.7 or later. I recommend you System 7 so that you can drag and drop.
The MB Stripper doesn't include Power Macintosh (PowerPC) Native Code. I think it works quickly enough under the emulation mode because of its simple features. I will consider, however, applying to PowerPC if you feel you absolutely need it.
The following is the machines I could confirm the MB Stripper works properly.
Macintosh Plus with System 6.0.7 and KanjiTalk 6.0.7
Macintosh SE/30 with KanjiTalk 6.0.7
Macintosh IIcx with KanjiTalk 7.1
Macintosh IIci with KanjiTalk 6.0.7 and KanjiTalk 7.1
Macintosh Classic II with KanjiTalk 6.0.7
Macintosh IIvx with System 7.1 and KanjiTalk 7.1
Macintosh Centris 610 with KanjiTalk 7.1
Macintosh Centris 660AV with KanjiTalk 7.1
Macintosh LC475 with KanjiTalk 7.1
Macintosh PowerBook 160 with KanjiTalk 7.1
Macintosh PowerBook 165c with KanjiTalk 7.1

7. Technical information
The MB Stripper supports both MacBinary I and II formats. However, some MacBinary II enhancements are ignored such as "Get Info Comments" or "Secondary Headers". I don't think they are so important because I didn't find any MacBinary files that includes such enhancements.
Developing Tool: THINK C 7.0.3
Developing Environment: Macintosh IIvx with System 7.1.1 and Japanese Language Kit
