Apple II Technical Notes _____________________________________________________________________________ Developer Technical Support Apple IIgs #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. +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | F| E| D| C| B| A| 9| 8| 7| 6| 5| 4| 3| 2| 1| 0| +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ |___________|_______________________|___________| Major Minor $A = Alpha Release Release $B = Beta $E = Experimental $0 = Final Figure 2-GS/OS Driver And SmartPort Version Numbers 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.

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.
