1.0  INTRODUCTION
     ------------

The purpose of this document is to define the compatible revision levels of
the 11/785 system and options.  Revision levels are tracked according to
DEC Standard 068.

A team composed of Engineering, Manufacturing and Customer Services will
review all changes and determine when the revisions in this document will be
changed.  This document is under ECO control and will be updated by
Engineering via the normal ECO process.

This RM document can be obtained in the following manner:

                (1) Order from Engineering Design Services by
                    P/N RM-11785.
                (2) VAX Library Microfiche
                (3) ENET - VOLKS::CLUSTER$REV:785REV.DOC
                        (Latest version always available)
                (4) Speed Bulletin #407

This document will be updated when an ECO is generated to a part that causes
the revision of the unit and/or combination of units to change.

Note that some 11/780 options that are used on the 11/785 do not follow the
revision tracking scheme as outlined in this document.  These are older
products that will be converted to DEC Standard 012 and 068 over time.


1.1  REVISION CONTROL
     ----------------

Definitions:  Part - FRU (module, backplane, power supply, etc.)

              Unit - Option (FP785, KA785)

              Combination of Units -  System (11/785)

All revisions noted in this document are MINIMUM REVISIONS.  Higher revisions
are compatible unless otherwise noted.


1.1.1  Part Revisions
       --------------

Part revisions are tracked according to DEC Standard 012 conventions. Each part
has an alphanumeric revision, up to a maximum of 4 digits.  When a part revision
changes, the alpha or numeric characters may change.  If the alpha character
changes, the new and old revisions are not interchangeable.  If the numeric
only changes, the parts are interchangeable within the common alpha revisions,
i.e. D1, D2 and D3 are all interchangeable.

Note that only the alpha character will be tracked for part revisions in this
document.  Minor revision (numeric) changes will not be noted.



                                        - 3 -
1.1.2  Unit Revision
       -------------

Unit and combination of unit revisions will be tracked via an alpha character
only; minor revision (numeric) changes will not be noted.


2.0  SYSTEM ID REGISTER
     ------------------

The System ID Register on the 11/785 is implemented in the same way as the
11/780 SID register.  It is accessible, as in the 11/780, by reading ID
register 03 or internal processor register number 3E from the console.
(See Section 1.2.1)

The register format for the 11/785 is as follows:


     31        24 23 22 21    18 17   15 14   12 11               00
     +---------------------------------------------------------------+
     | SYSTEM    | XX  |  XX    |   N   | PLANT |    SERIAL NUMBER   |
     |  TYPE     |     |----------------|       |                    |
     |           |     | SYSTEM REVISION|       |                    |
     +---------------------------------------------------------------+


2.1  How to read SID Register
     ------------------------

     Example:  (underlined portion is what you type)

>>>   E/ID  3
      ----  -

        ID   00000003   018032B2 *

        -or-

>>>   E/I   3E
      ---   --

        I    0000003E   018032B2 *

    *  (Sys type = 780; CPU type = 785; Sys rev = 0; plant = Franklin;
        last 3 digits represent serial number)


2.2  How to set SID Register
     -----------------------

KA785 Backplane Jumpers (located on the upper right hand corner of backplane)

        13    J13 R            0 = NI (Salem FA&T)    3 = FX (Franklin)
        14    J13 N            1 = GAlway             4 = FX (2nd series)

                               2 = C                  5 = F

        18    J13 D          System Revision Number
        19    J13 B            0 = Rev 0        .
        20    J12 VV           1 = Rev 1        .
        21    J12 TT           2 = Rev 2       15 = Rev 15

        22    J12 RR         CPU Type
        23    J12 NN           0X = 780         10 = 785

        24    J12 LL         System Type
        25    J12 JJ           1 = 780
        26    J12 FF           2 = 750
        27    J12 DD           3 = 730
        28    J12 BB
        29    J12 Z
        30    J12 X
        31    J12 V



                                        - 5 -

The above allows for the following distinctions:

        1. distinctions between 780s and 785s. (bit 23 set=785, clear=780)

        2. distinctions between manufactured 785s and 785 upgrades.
                (Manufacturing Plant Field, 5 = 785 upgrade, 3 or 4 = 785
                 original build)

        3. unique System ID Register for all 780s, 785s, and 785 upgrades
           manufactured by the corporation.


2.3  How to set SID Register for 11/785 Upgrades
     -------------------------------------------

Installation of a 785 Upgrade will require that Field Service set the serial
number jumpers on the new backplane to equal the serial number of the 780
being replaced.  This is done by removing from the KA785 J13-V through J13-VV
any jumpers necessary to duplicate the jumper configuration of the KA780
J13-V through J13-VV.  This will give the KA785 the same serial number
as the removed KA780 serial number.


3.0  11/785 UPGRADES (11/780 TO 11/785)
     ----------------------------------

All 11780 systems that are to be upgraded to an 11785 or 11/780-5 must be
at a minimum hardware rev 04.

In addition, the following minimum revisions are required:

                RH780 Rev 04, AA1 or B1
                MS780-C Rev 1B
                DW780 Rev 1B (Rev C1 for UDA50s)
                CI780- Rev C1

All existing revisions of all other VAX options are compatible.

NOTE:  RH780 REV 04, AA1, B1:

    The RH780 Rev 4 or AA1 is the minimum required for all 11785
    systems.  RH780 AA1 is the same as Rev 04.  AA1 implements Part
    Revision.  Rev B1 replaces the M8277 module with the M8274 module which
    is needed for high speed RP07s.  Note that the 11/780, 11780-5 and
    11/785 systems may contain a mixture of RH780 Rev 04 (AA1) and RH780 Rev
    B1 with no compatibility problems.

4.0  HOW TO READ REVISION MATRICES
     -----------------------------

This document is broken into two major sections:

        (1) Description of changes (History Page).

            This describes what parts/units were changed and why.  It will
            contain the following at a minimum:  ECO #, Problem corrected,
            symptom, new part revision, quick check, FCO # and any other
            comments that the team decides is necessary.

        (2) Matrices showing revision compatibilities.

            These matrices list the MINIMUM compatible revisions for each
            unit (option) or combination of units (system).  Higher revisions
            are also compatible unless otherwise noted.

To determine compatible revisions, begin with the highest level matrix to
determine minimum compatible revisions for the combination of units (system).
Then, refer to the revision matrices for each unit (option) to determine the
revisions for the parts contained in that unit.

As stated previously, this document does NOT track the numeric portion of the
part revision.  For instance, a part could have three usable and shippable
revisions - A1, A2 and A3 - but only "A" will show on the chart--all
three revisions are interchangeable.

5.0  UNIT REVISION MATRICES

This section contains the rev matrix charts and history pages for the
11/785 kernal options - 11/785, KA785, KC785, MS780-C/E/H.  The
matrices or revision charts for other VAX options that can be used on the
11/785 are attached at the end of this document.

|  Update the RM to reflect ECOs to the KA785 and FP785.  This brings the    |
|  11785 system to revision "01".  To set SID to revision "01" jumpers J12 TT|
|  and VV, J13 B and J13 F through J13 L must be installed.  Jumper J13 D    |
|  must be removed.  Manufacturing implementation date is October 29, 1984.  |

|COMMENTS:     An FCO will be implemented in the near future to upgrade all    |
|              FP785s from "C" TO "D".                                         |

|    Note:  Most E.Q. kits for FCO FP785-M00C1 contain rev "E1" of the M7541   |
|           and do not require upgrading.  However, it is important to check   |
|           the revision of the M7541 module before implementing the upcoming  |
|           FCO.                                                               |

6.0 APPENDIX

This section contains charts for options which can be part of an 11/785
configuration but do not have revision matrices today.  Unlike the
revision matrices which show only minimum useable revisions, these
charts show all compatible revisions. (They were taken from the Field
Service 11/780 Rev Con Document).

        MS780C-1.0 OPTION REVISION DESCRIPTION
        _____________________________________

        o   Creation date is Sept. 15, 1978

        o   This is the initial introduction of Option Level control for the
            MS780C and defines the minimum revision level necessary to support
            the first release of VMS (Release 1.0).

        o   All modules with previous revisions to those listed under MS780C-01
            must be updated to the current revision level.

        o   M8214 A,B module revisions are operational with VMS Release 1.0
            unless the system contains RM03 disks or 1Mbaud DMC11's. In those
            cases excessive data lates occur with the RM03 disks or line drop
            outs occur with the DMC11's.

        o   M8214 C module revision solves the above problems but must be used
            with M8275 D in the RH780 options.

        MS780C-1.A OPTION REVISION DESCRIPTION
        _______________________________________

        o   Creation date is April 13, 1979

        o   Change to M8213 board to get rid of problem where three longwords
            are returned for a quad read.  Problem occurs intermittently, only
            when running ECC tests at fast clock.

        o   M8213 eco should be installed along with M8271,M8273,M9044 eco's.
            Together these four changes make the 11/780 level 2A.

        MS780C-1.B OPTION REVISION DESCRIPTION
        ______________________________________

        o   Creation date January 12, 1981

        o   Fixes problem of intermittant or consistent failures when memory
            is expanded beyond 4 arrays - M8212 module.

        o   M8212 modules with National Semiconductor chips will not exhibit
            the problem.

        o   ECO 70-13625 TW005 to the backplane helps alleviates some
            single bit errors seen in the field.

| This is the initial introduction of the revision matrix for the DW780.       |
| This RM represents the current option rev. level shipping from mfg. in       |
| June, 1984.  Rev 01 in this doc. is the same as 1B (latest revision)         |
| defined in the CSSE 11780 revision control document.                         |

RH780-04 OPTION REVISION DESCRIPTION
------------------------------------

o          Creation date is July 1, 1981.

o          Corrects the following problems:

           1. Data transfers at 2.2 MB/SEC overrun the data buffers.  This
              revision must be installed prior to installation of an RP07.

           2. When doing odd byte transfers on the TU78, the last byte is
              dropped.

o          The two module ECO's (M8276 & M8277) must be installed in conjunc-
           tion with each other.

RH780-AA1 OPTION REVISION DESCRIPTION
-------------------------------------

o          This option revision implements part rev on the RH780 option.
           Note that compatible revisions for this rev are identical to
           Rev 04.

o          Rev AA1 (04) (i.e. RH780s containing M8277 modules) should be used
           on RH780s that are not running high speed RP07s.


RH780-B1 OPTION REVISION DESCRIPTION
------------------------------------

o          Creation date is December 1983 - manufacturing implementation.

o          M8274 module replaces M8277 module in this revision.  M8274 fixes
           problem with data being lost when running RP07s at high speed.
           An FCO was implemented in November 1983 to: (1) replace M8277s
           with M8274s when running high speed RP07s, and (2) add the M8274 to
           all RH780 CD kits.

           EQ-01217-01 - contents: 1 M8274 module.

o          11/780 systems may contain mixtures of RH780-Rev AA1 (04) and
           RH780-Rev B1 with no compatibility problems.

DR780-01 OPTION REVISION DESCRIPTION
------------------------------------

o           Creation date was May 1983.

o           Change to the M8299 module to fix a timing problem.  ECO also
            requires change to the DR780 microcode.  FCO will be implemented
            in Q1FY84.  FCO will be module rework and involves replacement of
            2 socketed FPLAs.

o           Microcode was changed as a result of this ECO.  New part number
            is AS-T392B-DE.  This was released in VAX Diagnostic Release 10
            (January 1983) and will be included in the E.Q. kit for this FCO.

o           NOTE THAT A SUPPLEMENTAL FCO WAS BE DONE IN OCTOBER 1983 TO
            CHANGE THE PART REV OF THE M8299 FROM "C1" TO "D1".  THIS WAS ONLY
            TO CORRECT THE REVISION; THERE WAS NO CHANGE IN THE CONTENT OF THE
            FCO.

CI780-01 OPTION REVISION DESCRIPTION
------------------------------------

o           Creation date was October 1983 - manufacturing implementation.

o           This revision change involves ECOs to the L0100, L0101 and
            L0102 modules as follows:

                L0100-TW003 - Constant carrier on one CI path may prevent use
                              of the other path.
                L0101-TW004 - 1.Lost CI packet under heavy load.
                              2.Incorrect microcode resulting in a loop at
                                address 24D
                L0102-TW003 - Intermittant local store parity errors.

o           FCO was implemented to upgrade all CI780 options and CD kits.
            Availability was November 1983.  Note that all CI780s in
            the cluster must be upgraded at the same time.

o           New microcode (CI780.BIN Version 2) required for this FCO.  This
            is included in FCO kit and can be ordered under PN AS-T213D-ME.

o           Diagnostics EVGAA and EVGAB updated in Release 14 (available from
            SDC November 5, 1983).  New version for both is 1.1.  These are
            included in the FCO kit - can be ordered under PN AS-T599B-ME.

            These FCOs should be installed prior to or during VMS V4.0
            installation.  Note that although VMS Release notes state that
            earlier revisions are acceptable, i.e. will probably work,
            engineering and product management have determined that the
            customer needs all these FCOs for acceptable cluster performance
            under VMS V4.0.

            Details of Cluster Rev D1 requirements were sent to all branch
            managers.

            Contact your regional/country FCO coordinator for ordering info
            on these FCOs.

            Refer to the VAXCluster Revision Control document for more
            information on Cluster Rev D1 requirements.

o           Minimum requirement for CI functional diagnostics (EVGAA, EVGAB)
            is 1.1.

CI780-D1 REVISION SUMMARY
-------------------------

o           Creation date was April, 1985 - Manufacturing ship date.

o           Option Revision "D1" involves a change to the microcode only.
            A functional problem was discovered in VAX cluster testing.
            The CI780 did not conform to Architectual Specification
            producing "MISCELLANEOUS ERRORS TYPE 12 & 13" causing VMS
            CI--PORT RE-INITS introduced by V3.0 microcode.

o           An FCO was implemented to upgrade all CI780 options to Rev "D1".
            Rev 4 microcode can be obtained in two ways:

                1.  Over the ENET - Copy VOLKS::CLUSTER$REV:CI780.BIN  +

                2.  Order EQ kits as follows:

CI780-E1 REVISION SUMMARY
-------------------------

o           Creation date was September 1985 (from Manufacturing).

o           Option Revision "E1" involves a change to the CI microcode only.
            New microcode is Rev 5. Problem fixed:  extensive in-house testing
            of very large VAXclusters showed that under specific conditions
            the CI780 interface will sometimes incorrectly recover from CI
            error conditions.

o           An FCO is being implemented to upgrade all CI780 options to Rev "E1".
            Rev 5 microcode can be obtained in two ways:

            1.  Over the ENET - Copy VOLKS::CLUSTER$REV:CI780.BIN +
            2.  Order EQ kits as follows:

CI780-F1 REVISION HISTORY
-------------------------

        o   Creation date is July 1986 - Manufacturing implementation date.

            This revision change involved an ECO to the L0101 module
            bringingthe module rev to "J1".

            *PROBLEM/CORRECTION
            L0101-MK009      1.numerous functional errors ("arbitration
                               timeout", internal queue retry error").
                             2.Need a variable sanity timer.
                             3.Need to check the "valid" bit when
                               referencing a cache buffer description.
                             4.Correct documentation errors.
                               Correction is V7.0 CI microcode and 6 proms.

       Note that the L0101 rev J1 and CI780.bin rev 7.0 must be used together.

       An FCO is being implemented to upgrade all CI780's (CI780-F1-I-005).

            L0101 MK010   -      1. Paths crossed, "reqid" sent on path a,
                                    response on path B.
                                 2. Clock the transmit enable flop correctly
                                    to prevent cluster hung.

       This ECO involves two etch cuts and two wire adds.
       It brings the L0101 to rev "K1". Revs "J1" and "K1" are both
       acceptable in CI780 rev "F1".


CI780-AA/AB REVISION H1
-----------------------

        o       Creation date is June 1987.

        o       This revision changed the CI780 from "F" to "H".

        o       This revision change involved an eco to the L0100 module
                bringing the module rev to "E".

        PROBLEM/CORRECTION

        L0100-MK006    1. Original 140 mhz clock and associated hardware has
                          tendency to drift off frequency.

                       2. Existing wires caused by eco #mk005 cause extensive
                          manufacturing costs. the following corrections are
                          implemented by this eco:

                          1. Change 140 mhz crystal to new hybrid oscillator
                             (p/n 18-23940-01) and delete unnecessary hardware.
                          2. Phase in new etch to remove wire's on module.




                                        - 35 -

        L0100-MK005    1. Major problems in the interface which would be highly
                          visible in large cluster configurations.

                          These problems include the following:

                          A) CI 20 self directed packet problem.
                          B) Arbitration problem.
                          C) SYNC detect pal could latch up under a flood
                             condition.
                          D) Implementation of the xtend hdr jumper was
                             incorrect.
                          E) Acknowledge turn-around and basic slot time
                             causing excessive collisions on the wire.
                          F) Correct trailer time to meet the spec.

                   1. The following corrections are implemented by this eco:

                        A) CRC byte counter reset now with (ILIB ABORT + INIT
                               FNC L) * - (ILIB INIT L).
                        B) First try flag is now incorporated to provide real
                           arbitration where the node is now synchronized on
                           loss of carrier and will obey the rules of dual
                           round robin arb.

                        C) New pal will be incorporated.
                        D) XTEND hdr jumper now functional.
                        E) Install a change to make alter delta time jumper
                           select A BASIC SLOT TIME OF 7 TO 10 CLOCK TICKS.

        *QUICK CHECK - (Module REV E1) L0100 with wire from a) e65.13 and
                           E177.13 B) E65.11 and E177.9

        DIAGNOSTIC EVCGD, V1.2 required for this eco.  Updated in diagnostic
        Release 26 (EVNDX 26).

                 L0100 jumper W1 (module rev E1) or S3 (module rev E2)
                 indicates the following conditions:

                 A) Jumper (W1) installed between e177 socket pins 11 and 12,
                    or switch (s3) open, disabled:

                   1) This makes the L0100 downwards compatible with rev D
                      L0100 modules, by maintaining the basic slot count to
                      the existing count of seven (7) ticks, acknowledge
                      turn-around remains the same as the original rev D
                      L0100's, and the trailer extension is not enabled.
                      With these eliminated, the eco'ed L0100 (rev E) will
                      maintain form, fit and function as the non-eco'ed (rev D)
                      modules.  However, it should be noted that the
                      following fixes will still be installed and be functional
                      in rev E, while in the disabled position:
                      new sync detect pal, CI20 fix, xtend hdr jumper, and XMIT
                      status bit 3.




                                        - 36 -

                 B) Jumper (W1) installed between E177 socket pins 9 and 10,
                    or switch (s3) closed, enabled:

                   1) Basic slot time is now implemented to ten (10) ticks.
                   2) Ack turn-around change fully implemented.
                   3) Trailer extension by two (2) bytes, fully functional.
                   4) Arbitration and first try flag full implementation.
                   5) New SYNC detect pal, xtend hdr jumper, CI20 and XMIT
                      status bit 3, will still be fully functional as above.
