TOPIC



    What versions of AppleTalk and ADSP are included with System 7 and later versions of System software? Are there any newer versions available? If so, what benefits do they provide?

DISCUSSION


    AppleTalk version 56 (part of System 7), the ADSP stack is integrated
    with the rest of the AppleTalk stack.

    The AppleTalk versions for System software 7.x.x are as follows:

    * System 7 and System 7.0.1 come with AppleTalk v56. System 7 Tune-Up 1.1.1
    does not change the version of AppleTalk installed.
    * System 7.1 comes with AppleTalk v57.0.4.
    * Both System 7 Pro and System 7.1.2 come with AppleTalk version 58.1.1.
    * System 7.5 comes with AppleTalk version 58.1.3

    The latest version of AppleTalk is v58.1.6 and is available on the PowerBook 190 and 5300 series computers. The latest Network Software Installer (NSI) is 1.5.1 which installs AppleTalk v58.1.5. AppleTalk v58.1.5 should be used except for the PowerBook 190 and 5300 series, or PCI-based Power Macintosh computers (7200, 7500, 8500, 9500) which requires Open Transport. (Search on Network Software Installer for specific content information.)

    Below is a history of AppleTalk and ADSP version since System 7.0.

    AppleTalk v57.0.1 and ADSP v57.0.1 changes
    ------------------------------------------
    * Added support for multiple DDP addresses on a single computer.
    * Some code was changed to be MC68040 friendly for the new Macintosh Quadra
    systems.
    * Minor modifications to retry timer handling were made in both NBP and
    ATP. This should reduce traffic due to retransmissions on slower network
    links (2400 to 19.2KB serial lines).
    * The Network Control Panel no longer allows you to select LocalTalk if the
    printer port is already open by another application.
    * Reliability and performance of LocalTalk on Macintosh Plus systems has
    been improved.

    AppleTalk v57.0.3 and ADSP v57.0.3 changes
    ------------------------------------------
    * Improved support for MC68040-based computers.
    * Support for the Macintosh PowerBook power-down modes.
    * Smaller RAM footprint in the system heap.
    * Performance improvements to the AppleTalk Transaction Protocol (ATP) to
    reduce network traffic when used with links such as AppleTalk Remote
    Access using 9600-bps modem.
    * AppleTalk Data Stream Protocol (ADSP) and AppleTalk Session Protocol
    (ASP) now support AppleTalk Remote Access. Sessions with computers on
    the remote end of a phone connection will be torn down when the phone
    connection is broken.
    * A bug was fixed in ATP which could cause an AppleShare client or file
    server to "hang" if any data wasn't received in the first attempt.

    AppleTalk v57.0.4 and ADSP v57.0.4 changes
    ------------------------------------------
    * A fix for a bug in ATP that could cause incoming GetRequest packets with
    a checksum to be dropped. This affects machines running fileshare if the
    client is sending packets with DDP checksums.
    * A fix for ADSP so that an openRetries count of 255 actually means
    "infinite retries", as specified in the documentation, rather than 255.
    * Improved performance under VM (virtual memory)
    * Improved File share and AppleShare performance over LocalTalk.

    AppleTalk v58 and ADSP v58 changes
    ----------------------------------
    * Adds support (instrumentation) for SNMP. Also includes continuing
    support for Apple's Router.

    AppleTalk version 58.1.1 (NSI 1.4.1-no change to ADSP)
    ------------------------------------------------------
    * A problem that existed with the LocalTalk SNMP byte counting code that
    would cause an occasional bus error was fixed. It was wrongly assumed
    that was ALWAYS a WDS pointer and that address was used to calculate the
    byte counts.
    * Check for Slotless networking devices when coming out of sleep for
    the PowerBook Duos.
    * Lap Manager only intercepts packets for SAP 0xAA or 0x00. An attempt will
    be made to deliver any packet for a destination SAP that is not 0xAA or
    0x00 to the SAP listener. If no SAP listener is found, then the packet
    will be ignored. A check in LLCAttach was added for duplicate SAP or SNAP
    addresses. If so, then an error is returned.

    AppleTalk version 58.1.4 changes
    --------------------------------
    * The LAP Manager was fixed to avoid sending corrupted TEST and XID
    response packets in certain heavy traffic situations.

    AppleTalk version 58.1.5 changes
    --------------------------------
    * An address-mapping problem that could cause slowdowns in EtherTalk or
    TokenTalk networks was fixed.
    * The LAP Manager was fixed to avoid sending corrupted TEST and XID
    response packets in certain heavy traffic situations.
    * A bug that passed a corrupted length indication to multi-node clients was
    fixed.
    * A VM problem that could cause hangs was fixed (this could also have
    occurred when Ram Doubler was active).
    * A LocalTalk problem on Power Macintosh computers was fixed that prevented
    LaserWriter Bridge from working properly.
    * An additional LocalTalk problem on Power Macintosh computers was fixed
    that caused slow performance when both LocalTalk and GeoPort were in use.

    AppleTalk version 58.1.6 changes
    --------------------------------
    * Included support for built-in infrared technology (IRTalk) found on the
    PowerBook 190 and 5300 series computers.
