- #100: VersionVille
-
- Written by: Matt Deatherage January 1991
-
- This Technical Note is all there is to know about versions, version formats and
- version numbers on the Apple IIgs.
- _____________________________________________________________________________
-
-
- Version Number Formats
-
- There are three kinds of version numbers on the Apple IIgs. Two of the three
- are documented elsewhere but are repeated here for convenience.
-
- System Tool Set Versions
-
- The Apple IIgs system tools use a one-word version number. The high-order four
- bits of this word have special meaning. Bits 8-11 are the major version number
- and bits 0-7 are the minor version number. This is illustrated in Figure 1.
-
- +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
- | F| E| D| C| B| A| 9| 8| 7| 6| 5| 4| 3| 2| 1| 0|
- +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
- | |_____|| Major | Minor |
- | | | Release | Release |
- | | |___________|_______________________|
- | |
- | +---- 1 = Special Features
- +---------- 1 = Prototype
-
-
- Figure 1-Toolbox Version Numbers
-
- Note that this definition is different and supersedes the definition in the
- Apple IIgs Toolbox Reference for system tool sets. Previous documentation
- reserves only bit 15 as the prototype bit; this has been expanded. Bits 14-12
- of user tool set version words have no special meaning; they are still part of
- the major release.
-
- Note: When comparing the major and minor release version numbers to check the
- installed version of a system tool, mask off bits 15-12 first (for
- example, by using an AND #$0FFF instruction).
-
- SmartPort Or GS/OS Driver Versions
-
- GS/OS drivers and SmartPort firmware drivers use an alternate one-word version
- number, described in Figure 2.
-

- Major Minor $A = Alpha
- Release Release $B = Beta
- $E = Experimental
- $0 = Final

-
- Apple IIgs Long Version Format
-
- Long version format is a 32-bit (two-word) format similar to the standard
- Macintosh version numbering scheme defined in Macintosh Technical Note #189,
- Version Territory, except the four bytes are stored least significant byte
- first, as is standard on the Apple II, and the values of the stage are
- different. Figure 3 shows the format of a long version.

- | Major version | Minor v. | Bug vers. |
- +-----------------------+-----------+-----------+
- Major version |Minor | Bug version

- $25 = Version 25 |Example: | $4 = Version
- |$0 = Vers. | x.y.4
- x.0

- | Stage | Must be zero | Release version |
- +--------+--------------+-----------------------+
- Stage: | | Release version (2
- 001 = develop | | digits, BCD)
- 010 = alpha | | Example:
- 011 = beta | | Long version value of
- 100 = final | | $25048006 = Version
- 110 = release 25.0.4f6
-
- Figure 3-Long Version Numbers
-
- Long version format allows for bug versions, unlike toolbox versions. Also, you
- can do unsigned long comparisons of long versions to determine which revision is
- later.
-
- Note: If the version stage is 101 (release), the release version must be zero.
- For example, you may not have version 25.0.4 release 16. "Release
- version" implies that the product is no longer under development and has
- no developmental version numbers.
-
-
- System Version Numbers
-
- The most important of the numerous version numbers in the system are the system
- tool version numbers. These numbers, passed to LoadTools, LoadOneTool or
- StartUpTools ensure that you're getting at least the version you want, or maybe
- a later one. This mechanism is your primary defense against old system
- software-by requiring the latest tool versions in your application, you are
- notified by the Tool Locator early in your program if the system has the latest
- system software installed or not.
-
- Note that ROM 1 and ROM 3 have different version numbers for seven tools under
- 5.0.4-QuickDraw II, the Scheduler, ADB, SANE, Integer Math, Text Tools and the
- List Manager. In each case, the ROM 01 version is lower and should be used in
- your LoadOneTool, LoadTools or StartUpTools calls.
-
- The current revision of Apple IIgs System Software is 5.0.4. The only system
- tool to change from 5.0.3 to 5.0.4 is QuickDraw Auxiliary, which changed to
- version 3.3. Assuming a correct installation, requiring QuickDraw Auxiliary 3.3
- in effect requires System Software 5.0.4.
