CD-ROM Standards Used
---------------------
By Wayne Brissette
This article contains a list of CD-ROM Standards, or formats, and their definition.
You may hear or see several terms used to define CD-ROM discs and drives. These include Red Book, Yellow Book, White Book, and Green Book. Some of these standards, such as the White Book, are derived from previous standards, but with added features.
* Red Book
The Red Book specification is for digital audio CDs. All audio CDs use this specification to assure that any audio CD-ROM in the world works with any audio CD-player. The Red Book specification was developed by Phillips and Sony.
* Yellow Book
The Yellow Book specification is used for computer-based CD-ROMs. The Yellow Book specification only defines the physical arrangement of the data on the disc. Other standards are used in conjunction with the Yellow Book to define directory and file structures. These include ISO-9660, HFS, and Hybrid HFS-ISO. Sector formats are defined as Mode 1, Mode 2, and CD-ROM/XA.
* ISO-9660
This file system standard is a "lowest common denominator" format. It only allows for an 8.3 filenames (EIGHT__8.TXT). There is an extended ISO-9660 file system, called the Rock Ridge extension, used primarily for UNIX CD-ROMS that allows for longer UNIX file names and directory structures.
* HFS
This file system is designed to support Macintosh features not supported under the ISO-9660 standard. This includes longer file names (up to 31 characters), custom icons, and other Finder features such as comments and labels.
Hybrid HFS-ISO
This file system is a combination of ISO-9660 and HFS. This format is used by CD-ROM developers on products designed for both the Macintosh and MS-Windows or UNIX platforms.
* Mode 1
Mode 1 CD-ROMs contain only computer data, and have 2048 byte sectors.
* Mode 2
Mode 2 CD-ROMs contain compressed audio data and video/picture data, and have 2324 byte sectors. Mode 2 sectors also contain end-of-record markers, interrupt triggers, and data type specifications.
* CD-ROM/XA
CD-ROM/XA (CD-ROM Extended Architecture) is an extension of the Mode 2 format. Like Mode 2 it contains compressed audio and video/picture data. The CD-ROM/XA format however offers the ability to interleave the Mode 2 compressed audio and Mode 2 data sectors.
* White Book
This specification covers the Video CD format.
* Green Book
This specification builds on the Red Book and the Yellow Book, and is designed for CD-I discs (Compact Disc-Interactive).
* Orange Book
This specification covers writable CDs, including CD Recordable (CD-R), magneto-optical cartridge systems and single- and multi-session recordings.
* CD+ (CD Plus)
This specification is still being worked on by both the computer and music industry. It is a derivative of the CD+MM format, which combines computer multimedia elements with a standard audio CD-ROM. With the current CD+MM format, Track 1 contains the computer data, and when placed into an audio CD-player, Track 1 must be skipped. The goal is to have a CD-ROM that will contain both audio and computer data on one disc, and when placed into an audio CD-player plays only the audio tracks. All computer data is ignored without any manual assistance.
Why Microsoft Word Does Not Show in the Macintosh Easy Open List
When attempting to open a document with an unknown creation type, or with a creation type for which the appropriate application is not available, Microsoft Word does not show in the list of applications provided by Macintosh Easy Open dialog. The reason Translation Manager (Macintosh Easy Open) behaves like this is because it only uses the 'FREF' resources if the application does not have an 'open' resource. Macintosh Easy Open uses two new resources. These are the 'open' and 'kind' resources.
* The ‘open’ Resource
The 'open' resource is supposed to contain a list of file types that the application can open without any external help, like MacLinkPlus. Another purpose of the 'open' resource is to allow an application to have custom icons for files that it does not want the user to open and prevents the Finder from launching the application when the user tries to open one of these documents. For example, an application can have a settings file with a custom icon by putting the type of the settings file in the 'FREF' and 'BNDL' resources but by not putting the type in the 'open' resource, the Finder does not launch the application if the user tries to open the settings file.
* The ‘kind’ Resource
The 'kind' resource contains kind strings the Finder displays. For example, the kind string for a read only SimpleText document is "SimpleText read-only document."
Some applications have a 'FREF' resource for files of type '****'. This is wildcard file type and means any file can be dropped on the application. However, in the 'open' resource, Macintosh Easy Open treats this as a file type and not a wild card type. Microsoft Word's 'open' resource only contains the '****' file type. For example, when attempting to open a file with a creator type of '****', Word shows up in the Macintosh Easy Open application list. However, when attempting to open a file with a creator type of 'ZZZZ', Microsoft Word was not in the list of applications.
According to the Macintosh Easy Open engineer, having only '****' in the 'open' resource is a mistake. However, the Translation Manager documentation does not indicate if '****' is a valid file type; there is no mention of wild card file types. Wild card file types are described in the Finder Interface documentation.
It appears Microsoft thought that by putting the wild card file type in the 'open' resource, Word would show up in the list no matter what file the user was trying to open. However, Macintosh Easy Open does not support wild card file types. Other applications have the '****' type in the 'open' resource but they also have other types as well. Microsoft Word seems to be the only application that has only the '****' type in the 'open' resource. Please contact Microsoft at (206) 454-2030 for additional help with this problem.

Printing Sharing Between GX and Non-GX Users
--------------------------------------------
From the Technical Information Library
Sharing printers between QuickDraw GX and non-QuickDraw GX systems is not really possible. The "not really" is primarily because of the third point below (describing a shared PostScript network printer).
* Share this Printer Option Not in Printing Menu
The option of Share this printer is NOT located in the Printing menu. When you select a desktop printer, the sharing option is located in the File menu. You share a desktop printer just as you would any other volume or folder: by selecting the printer icon, then choosing Sharing from the
File menu, and checking the Share this item box.
* Shared QuickDraw Serial Printer Options
When a QuickDraw serial printer is shared, the option Non-QuickDraw GX systems may also use this printer is grayed out. This is because the previous implementation of print sharing with PrinterShare (also known as GrayShare/ColorShare) is not compatible with QuickDraw GX. They utilize different techniques for sharing and also provide different functionality. QuickDraw printer, all clients MUST have QuickDraw GX installed, and Server must be selected in the popup field on the right side of the Chooser's window.
* Shared PostScript Network Printer Options
When a PostScript network printer is shared, the option Non-QuickDraw GX systems may also use this printer is available and works EXACTLY as the Bypass option in the AppleShare PrintServer. This lets all clients (QuickDraw GX and non-QuickDraw GX) see the printer and print to it WITHOUT having to go through the QuickDraw GX system that has captured it. For non-QuickDraw GX clients, they can directly see the printer in the Chooser. For QuickDraw GX clients, they can see the printer if they select AppleTalk in the popup field on the right side of the Chooser’s window.
* Summary
In summary, when a printer is "Shared" by the QuickDraw GX computer that has captured it, to print to that printer the client Macintosh computers MUST have QuickDraw GX installed. The only slight exception to this is when a PostScript network printer is captured and the Non-QuickDraw GX systems may also use this printer option is enabled, both QuickDraw GX and non-QuickDraw GX clients can see and use the printer.
NOTE: In this case, there is no way to require non-QuickDraw GX users to have a name and password. This is because the QuickDraw GX "server" is being bypassed. There are no plans to support name/password security for non-QuickDraw GX systems due to the differences in "print sharing" architectures between QuickDraw GX and non-QuickDraw GX systems.
Global Village Modems -- Questions and Answers
----------------------------------------------
By Robert Dorsett
Here are answers to frequently asked questions about Global Village modems, which are bundled with Macintosh Performa computers.
Question:
Did my Macintosh Performa computer come with software that let me connect to a local bulletin board system (BBS)?
Answer:
All Performa computers come with a "Works" style package, such as ClarisWorks, Microsoft Works, Symantec Greatworks, or WordPerfect Works. These applications include a terminal emulator, usually under the heading of "communications". They let you use your Macintosh computer as a terminal. See your "Works" documentation for more information. There are also many software packages available commercially and as shareware. You can access the third-party software directory on eWorld (eWorld shortcut "shareware") to locate shareware software. You can also access the Redgate Product Directory (eWorld shortcut redgate) on eWorld, which contains information on over 7000 Macintosh products.
Question:
I have a TelePort Bronze modem, and it does not appear to receive faxes. What should I do?
Answer:
Your modem is capable of receiving faxes, but your computer must be equipped with software that can support this capability. Your computer currently comes with a "send only" capability. The "receive" fax capability is sold and supported directly by Global Village. Please contact their sales department at 800-736-4821 for sales and additional information on this product.
NOTE: All Macintosh Performa 6100 series computers, the Performa 637, and the Performa 560 come with a "receive" capability as part of the software bundle. The following computers are in the Macintosh Performa 6100 series: Performa 6110, Performa 6112, Performa 6115, Performa 6117, and Performa 6118.
Question:
I have a Macintosh Performa 6100 series computer with a TelePort Gold II modem, and I cannot connect to eWorld at 14.4 Kbps. What should I do?
Answer:
You should contact the eWorld Assistance Center at 800-775-4556. They have a version of the eWorld software they can send you, which has special initialization strings for the Global Village Gold II modem. With the new eWorld software, you should be able to connect at 14.4 Kbps, provided that you are calling the correct dial-up number.
Question:
Can I upgrade my TelePort Bronze to a faster modem?
Anwer:
Global Village offers an upgrade program for Performa customers. For more details, call their sales number at 800-736-4821.
Question: Where can I obtain the Global Village 2.5 upgrade, and what does it do?
Answer:
Global Village sells this upgrade directly to their customers for a nominal fee. You need to call their sales number at 800-736-4821 for pricing and specifications.
Question:
I am having trouble connecting to my internet service provider with my PPP and SLIP utilities. How can I correct this?
Answer:
If the modem works in other respects, such as connecting to eWorld, online services, BBSs, or as a fax modem, then the difficulty is likely caused by the configuration of the Internet software. You should contact your internet service provider for support in configuring the software.
Question:
I bought a new fax modem, and I get an error message stating the serial port is in use whenever I try to use eWorld or try to fax. What should I do?
Answer: The modem port can only be in use by one application at a time, so you need to make sure that no other program (such as eWorld) is currently running. If the problem persists, the old fax software may be conflicting with your new software. To correct this, you should remove the old fax software and restart.
- If you have a Global Village TelePort Bronze, the old software is stored here:
- System Folder: Apple Menu Items: Fax Center
- System Folder: Extensions: GlobalFax
- System Folder: Control Panels: TelePort/Bronze (called "Fax Modem" on some computers)
- System Folder: GlobalFax Files
- System Folder: GlobalFax Personal
- If you have a Global Village TelePort Gold II, the software is stored here:
- System Folder: Apple Menu Items: Fax Center
- System Folder: Control Panels: TelePort Serial
- System Folder: Extensions: Global Village Toolbox
- System Folder: Extensions: GlobalFax
- System Folder: GlobalFax Files
- System Folder: GlobalFax Personal
NOTE: "GlobalFax Files" contains any faxes you may have sent with the Global Village modem. You may wish to retain that folder, and Fax Center, so you can review any messages you may have sent if necessary.
If you move all of the above files to a single folder, they are "de-activated" by the system software after you restart. There is no need to throw them away, unless you want to reclaim the hard disk space. If you throw them away, make sure you have made a backup of the software or your System Folder. If this does not solve the problem, it could be a configuration issue with your third-party software, and you should contact the manufacturer for support.
Question:
I would like to receive faxes, but do not want to leave the computer on. Can I do this?
Answer:
No. The computer must be on and the fax software must be loaded in order to receive faxes.
