    Right on Dave.....
    
    
    Only problem is,they program them with all this funny stuff like
    RSTS and RSX....
    
    
    
    
6.5VAX or VAE?KERNEL::PLANKWed Mar 08 1989 17:335
    In that case VAX is spelt wrong. It should be a VAE.

    I suppose really the VAX (VAE) range could be called BGC's .
    
    BGC = Big Grey Cupboard
    
    Uvaxes could be LGC's and workstations could be PGC's ( Piddly Grey
    Cupboards )

HI FOLKS,
       THIS MAIL IS TO ASSIST NEW ENGINEERS AND REFRESH THE MEMORIES OF THE
"OLD LAGS"

HUNG 1170
=========

BEFORE HALTING THE CPU AFTER A ^P DO:-

a......"U" (TO LOOK FOR BR'S,BG'S ETC....ALSO AC,DC LO).
           YOU MAY SEE MSYN,SSYN ETC WHICH ISN'T A PROBLEM BUT YOU
           SHOULDN'T SEE INTERRUPT SIGNALS ON A RUNNING SYSTEM.

b......"T" (TO LOOK FOR ADDR OR PAR ERRS).
           IF EITHER IS SET CHECK $44,$66 ECT.


C......IF "U' AND "T" FAIL TO INDICATE A PROBLEM,THEN HALT THE CPU AND USE
       "T" AGAIN TO SEE IF THE "PAUSE" BIT IS SET,IF IT IS THE USE "3M"
       TO FIND THE MICRO ADDRESS.YOU WILL THEN HAVE TO CHECK THE 1170 "FLOWS"
       TO FIND OUT WHAT TYPE (PAUSE,BUST ETC) OF MICROWORD IT IS.


d......IF "T" INDICATES IT IS NOT A "PAUSE" MICROWORD AND "3M" IS NOT INDICATING
       THE CONSOLE MICROWORD (ie..170),YOU WILL STILL REQUIRE FOR FIND OUT WHAT
       TYPE OF MICROWORD IT IS.




THESE ARE GENERAL RULES TO INDICATE WHICH FRU:-

1... IF AN INTERRUPT IS THE REASON FOR THE HANG THEN A DEVICE AT THE 
     HIGHEST "BR/BG" LEVELIS SUSPECT (WE CANT IDENTIFY IT FURTHER).
     (IF YOU HALT THE SYSTEM YOU WILL NEARLY ALWAYS SEE BR'S [NOT A PROBLEM]).

2... IF ITS AN AC/DC LO PROBLEM,WE CANT GET ANYMORE FROM IT.


3...IF IT IS STUCK IN A PAUSE AND ITS A PAUSE MICROWORD (INTERRUPT OR CACHE 
    CYCLE) 

   CACHE
   =====

   M8139 OR M8142 SUSPECT (FOR AN OGOING PROBLEM THE OTHER 3 CACHE MODULES
                           CAN BE RESPONSIBLE).

   INTERRUPT
   =========

   M8139 OR M8136


4... IF IS STUCK IN A PAUSE BUT THE MICRO ADDRESS IS NOT A PAUSE MICROWORD

   M8139 OR M8123 (KB11-C),M8133 (KB11-B)


5...IF THE CPU IS NOT A PAUSE STATE AND IS STUCK AT ANY MICRO ADDRESS THEN
    THE M8139 IS SUSPECT OR ITS POWER SUPPLIES (+/- 15V).


IF THE CPU HALTS
================

CHECK "T" AND "U" FOR ANY OF THE OBVIOUS FAULTS AND ALSO CHECK WITH THE
CUSTOMER WHETHER V000377 WAS PRINTED ON THE CONSOLE (POWER INT/EXT SUSPECT).

CHECK THAT "MEMORY MANAGEMENT" IS ON,IF IT IS AND THERE ARE NO OTHER ERRS,THEN
CHECK THAT THE "RELOCATION" WAS CORRECT,IF IT WAS OFF ON A RUNNING OPERATING
SYSTEM THE M8137/M8138 (KB11-B),M8138-YA (KB11-C) ARE SUSPECT.






************ IF IN DOUBT.........ASK !!!!!!!!!!!!!!!!!! *************




I HOPE THAT YOU WILL FIND THE ABOVE HELPFUL AND USEFUL.

    Architecture: Single-accumulator, 1's complement arithmetic.
Certain instructions automatically convert -0 to +0. The IO
register functions as an MQ register for mul and div operations,
as well as the path for all Input-Output transfers. 

    Input/Output: All I/O via the IO register.  I/O scheme was
radial - a special plug was wired for each IO device used in the
system. Standard options:
     	Paper Tape Reader (Photoelectric,400 bytes per second)
     	Paper Tape Punch (63 bytes persecond)
     	Typewriter (Soroban modification of IBM Selectric typewriter)

    Development History: The PDP-1 was a follow-on the Lincoln 
Laboratories TX-2, and was the effort of Ben Gurley.  The CPU 
used standard 1000 series modules (the AC consisted of 1201s, the 
IO and MB were 1209s).  Memory modules were, of course, developed 
specifically for the PDP-1.  

The prototype was checked out in late 1959/early 1960.  I 
remember seeing it when I came for my interview in early 1960.  
This prototype consisted of a detached console; detached 
peripherals, and LOTS of large cables to connect everything 
together.

    Production History: The first production PDP-1, largely a
duplicate of the prototype, was built for BBN in the summer of
1960.  Shortly thereafter, an important decision had to be made -
do we build the PDP-2 and/or PDP-3 or concentrate on the PDP-1. 
Ken was most insistant that we concentrate on the PDP-1.  As
usual, he was right.  

The PDP-1 was redesigned to make it easier to build.  The entire
basic machine was put into four equipment bays bolted together. 
Several cosmetic changes were made at the same time: the "digital" 
seven block logo first appeared on the front of the redesigned
machine; the brown tweed paint which had been standard on the lab 
modules and the first two machines was scrapped in favor of blue.

I'm not sure of the total number of PDP-1s built - if memory 
serves me correctly, it was somewhere in the range of 50 - 60.

	PDP 11  console interrupt test routine.
	~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

	Written by: 	John Strahorn
	Source:		CSC Viables/UK
	Date:		20-June-1991


Forward:
~~~~~~~

	The following code is a simple interrupt driven program that
	waits for interrupts from the console terminal keyboard.The
	program will print the character represented by the depressed
	key. It is a good test routine to check TX & RX lines on both
	the console terminal & console communication card port.
	

	This code is position dependent.(ie ...The following program
	must start at location 1000 unless the code is modified).



Location	Instruction/operand	Code		Description
~~~~~~~~	~~~~~~~~~~~~~~~~~~~	~~~~		~~~~~~~~~~~

1000		MOV #100,@#RCSR		012737		Set bit 6 in Console
1002					   100		Receiver status reg to
1004					777560		enable interrupts.

1006		MOV #1016,@#60		012737		Load vector location
1010					  1016		60 with the service
1012					    60		routine address.

1014  LOOP:	BR  LOOP		   777		Wait loop Branching
							to itself.(Waiting
							for interrupts.)

1016  SERVICE:	MOV @#RBUF,R0		013700		Read input character
1020					777562		from keyboard.Reading
							this reg enables next
							interrupt to be recei-
							ved.

1022  TEST:	TSTB XCSR		105737		Test bit 7 in transmit
1024					777562		status reg to see if
							ready to send character
							to console display.

1026		BPL TEST		100375		If bit 7 is not set
							then test again.

1030		MOV R0,@#TBUF		010037		Send character to 
1032					777566		console display.

1034		RTI			     2		Return from interrupt.

1.0     SERVICE BUSINESS PLAN

1.1     EXECUTIVE SUMMARY

1.1.1   PLAN SUMMARY

        The Setasi PEP-70 2mb,4mb and HyperCache HC70 subsystem is being
        introduced into DIGITAL's VES offerings as a "CAT-A" worldwide product
        set.  These products will replace the existing MK11 memory
        configuration in the 11/70's.

---))   The Setasi UFUM 256kb, 1mb, and Setasi SC44 Cache subsystem are being
        added to the PDP Enhancement program offerings.  As is the case with
        the prior products, these options allow customers to update their aging
        memories.  The systems directly effected will be PDP 11/34, 35, 40, 45,
        50, 55, 24, 44.  The options are limited to Unibus systems only, and
        replace the MS11 products.

        In an effort to retain Customer Service account presence, DIGITAL will
        resell these options through the DAS (Digital Assisted Services) group,
        for both DAS customers and regular contract customers.  DIGITAL will
        not be a VAR, and the Setasi labels and etchings will be present on the
        products.  There will be no DIGITAL labeling on the product itself.

        This combined sales and service effort has been identified by the
        Corporation as critical in maintaining the PDP Unibus base as well as
        incremental re-acquisition of past customers.

1.1.2   BUSINESS IMPACT

        As the MK11 memory units continue to age, their problem free life
        decreases.  In order to retain customer satisfaction a replacement
        option is needed.  The Setasi offerings are such products that have
        both an existing track record of success and a newer technology form
        factor.

---))   The MS11 memory units that the UFUM products replace, are aging and
        their reliability decreases.  The same problems are being faced by all
        customers owning older PDP Unibus memory subsystems.

        Any loss in the 11/70 base for Customer Service is a potential loss of
        sales of new technology.  The risk in not providing our customers with        an option to the failing MK11 is therefore unacceptable.





        The approved Worldwide contract prices for the options is as follows:

        DIGITAL ID       VENDOR ID         BMC        DSMC       INST

1.1.3   KEY and CRITICAL ITEMS

        o  MTTR must be kept to a minimum

        o  Field Engineer should be knowledgeable with PDP 11 technology

        o  Any system downtime is unacceptable to the customer






2.0     MARKETING PLAN AND ANALYSIS

2.1     HARDWARE SALES FORECAST

        There have been approximately 1,000 PEP70's sold since product
        introduction in 1987.  All product is in Digital 11/70's.  The sales
        life cycle of the product is dependent upon the number of MK11's still
        in service, estimated to be about three more years.  The service life
        cycle is dependent upon the 11/70's life, and is not calculable at this
        time.  A level ramp in sales is anticipated with the highest point
        possible in Q2 FY91.

---))   The UFUM product set is newer in life cycle than the PEP series.  It
        is estimated that there will be a worldwide sales of approximately 4000
        more units.  There could be a slight bubble in the sales effort in the
        second or third quarter of sales, but the anticipated ramp is level.

2.2     SERVICE PRODUCTS

        For units sold through the DAS channel, Warranty, Basic and DECservice
        will be available on-site.  For units purchased through Setasi or its
        authorized distributors, Basic and DECservice on-site will be
        available.  In either case, Installation will be available for the
        approved price.

2.3     COMPETITIVE ANALYSIS

        DIGITAL Customer Services will be the only organization authorized by
        the manufacturer to do on-site service for the options.  Even with this
        authorization, DIGITAL does not retain any exclusive rights to service.

        In some cases customers will opt to hold a hot spare on site and
        utilize a return to factory option that Setasi offers.

        While service on the options may remain somewhat non-competitive, the
        competition for overall service on the PDP system level is fierce.






3.0     SERVICE OPERATION PLAN

3.1     PRODUCT DESCRIPTION

        The PEP70/2 and 4mb memory boards are plug and play compatible modules
        that reside in the CPU backplane.  Upon installation of this option,
        the existing MK11 memory and associated cabs, hardware and cables are
        eliminated.  The option will increase CPU and BUS throughput and is
        fully compatible with all present hardware and approved operating
        systems.

        The Hypercache HC70 is a four board standard hex height option.  This
        option will replace the existing cache modules, board for board in the
        11/70 CPU.  This option greatly improves the systems efficiency in data
        retrieval processes.

---))   The SC44 is a two board 1 MB replacement cache for existing 8 KB cache
        on the 11/44. This option greatly improves the system efficiency in
        data retrieval processes.

---))   The UFUM is a single board ultrafast memory. The UFUM-256k is a 256KB
        memory for 18 bit addressing on PDP-11 Unibus systems (11/34, 35, 40,
        45, 50, 55). The UFUM-1MB is a 1MB memory for 22 bit addressing on
        PDP-11 Unibus systems (11/24, 44).

3.1.1   ARCHITECTURE

        These options are both fully compatible with all approved PDP-11
        operating systems and hardware.

3.1.2   PHYSICAL DESCRIPTION

        The PEP70/2 and 4mb are each standard hex height boards, while the HC70
        consists of four individual hex height boards:

3.3     SUPPORT SERVICE PLAN

3.3.1   SUPPORT STRATEGY

        The strategy is to utilize the existing method of support for the
        PDP-11 products. The variant is the replacement of central engineering
        with the vendor.  All geographic escalation procedures should be
        exhausted before contacting Setasi.

        Setasi will maintain a 24 hour 7 days a week hotline.  In non-prime
        hours, the call will be forwarded to the appropriate person via
        internal call paging at the vendor site. (305) 584-4446.


        EUROPEAN SUPPORT STRATEGY
        -------------------------

        Support escalation will be in accordance with "VES - TSSE
        INVOLVEMENT FOR VES PRODUCTS"

        This document is available on ACCESS, record 14391.

        It basically states, normal Subsidiary routes up to Country level,
        problems not resolved at this level should be passed to CSSE-E VES
        Group for escalation and management.

3.3.2   SUPPORT SKILLS

        The support engineer should be fully conversant in the operation of the
        PDP11 and Unibus technology.  They should also have the Installation
        document available for reference.

3.3.4   FCO STRATEGY

        Customers may request Digital install an FCO.  The installation of this
        FCO should be at the mutual convenience of the Customer Service branch
        and the customer.  The customer is responsible for procuring said FCO
        and will be charged the appropriate labor rate for its installation.

        DIGITAL will install SAFETY FCO's at our own expense in order to
        expedite its installation and insure the maximum avoidance of any
        personal injury.


        ***** EUROPEAN FCO STRATEGY STATEMENT *****

        REVISION CONTROL (FCO'S)
        -----------------------

        CSSE-E VES Group will be the focus of all VENDOR change activity.

        Vendor FCOs will be evaluated by CSSE-E VES Sustaining. All Product
        Safety FCOs will be installed at DIGITAL's expense, using VENDOR
        supplied solution's. Other FCOs may be installed, if cost effective
        and failure to do so may severely impact Service Delivery or, where
        VENDOR Product's adversely affect the performance of DIGITAL's own
        products.

        Other VENDOR FCOs may be identified in articles submitted to the
        TIMA/STARS [VES] Problem/Solution database.






3.4     LOGISTIC MATERIAL INFORMATION

3.4.1   LOGISTIC STRATEGY

        The logistics strategy is to purchase and deploy the necessary spares
        to meet contracted response time requirements.

3.4.2   DISTRIBUTION STRATEGY

        It is intended that spares to support the Setasi products will be
        purchased by and distributed from  Stockroom 17 in Andover MA. to the
        servicing SDU's/DLO's/ILO's and subsidiaries.

3.4.3   STOCKING STRATEGY

        Central stocking will be provided by Stockroom 17 in Andover MA.  The
        servicing SDU's (U.S.) and Subsidiaries (GIA-Europe) should make local
        stocking decision based upon contract base and response time
        requirements.

        The Nijmegan ILO should order and stock replenishment spares for the
        European subsidiaries. Nijmegan should order its spares inventory from
        Stockroom 17 in Andover MA.

3.4.4   SOURCING STRATEGY

        Seed stock spares should be sourced from Stockroom 17 in Andover MA.

        FRU's in support of field consumption should be ordered from Stockroom
        17 in Andover MA.

3.4.5   REPAIR STRATEGY

        The repair strategy is to replace the defective FRU's at the customer
        site. R&R qualified FRU's should be returned to stockroom 126 for
        credit. Stockroom 126 will forward the defective FRU's to the vendor

4.0     SERVICE DELIVERY

4.1     SERVICE DELIVERY METHOD

        The method of service for these Setasi options will be On-site,
        utilizing the existing PDP 11 diagnostic suite.  If the Setasi option
        is found to be failing, board replacement is the strategy.

4.2     PROBLEM MANAGEMENT SYSTEM

        Problems relating to the service of the Setasi options should follow
        the standard geographic Management Action Planning (MAP) procedures as
        appropriate.

4.3     PRE-CONTRACT INSPECTION

        A visual inspection of the product should be done to assure quality
        engineering.

4.4     OPTION LEVEL - SWAP STRATEGY

        The PEP70 2 and 4mb are complete options and should be swapped out if
        it is failing.  The HC70 is a four board option, and therefore the
        failing module board should be swapped out, and only if necessary the
        entire four board option be replaced.

---))   The UFUM options are each single board options that should be swapped
        out if failing.  The SC44 should be swapped as a whole option, as well.

4.6     REVISION MANAGEMENT

        Setasi will supply DIGITAL with copies of any FCO's and product
        enhancement bulletins.  MVDS/CSSE will act as the focal point for this
        information and together with the Product Manager and the
        Maintainability Engineer assign an applicable impact code.  The
        distribution of the vendor FCO will be through Speed Bulletin, BLITZ,
        FPR's and Product Microfiche.

        VFCO's URGENCY AND FIELD APPLICABILITY

        M= MANDATORY - For use as highest urgency and usually is relevant to
        hazards involving safety to operator user or service personnel.
        DIGITAL pays for labor and distribution of parts and documentation

        R= REQUIRED - For use as a high priority.  Functional or performance
        enhancement to vendor equipment product.  Labor, parts and distribution
        will be reviewed for impact on a case by case basis.  Review will
        include impact summary and will determine who pays for implementation;
        DIGITAL or customer, and the urgency of implementation.

        I= IMPROVEMENT - Enhances the option performance.  CSSE/MVDS will
        review on a case by case basis.

        Any vendor FCO distributed without these codes are considered to be
        non-essential and of minimal impact.  CSSE/MVDS will make these
        available via Speed Bulletins and Microfiche for informational purposes
        only.  Any installation of these FCO's must be at prevailing T&M rates
        and at customer's specific request.

PRESS RELEASE

UKPR441 -- September 15 1993
For further information:
    Kevin Taylor 0707-374291 or Graham MacKenzie 0707-374205

In line with its strategy of servicing its customer base through a
focused distributor channel, Digital Equipment Company has appointed
Mentec Computer Systems Ltd (MCS) as sole distributor for the Digital
PDP-11 product range in the United Kingdom and Ireland.

Over the past ten years, Digital has announced new technologies -
including the VAX architecture and most recently Alpha AXP - to which
many of its PDP-11 customers have ported their applications.  However
a significant PDP-11 customer base still remains, mostly in the
embedded applications areas.

                                                            
"More than 20 years after its original release, there are still some
40,000 PDP-11s running businesses - a testament both to the popularity
of the PDP-11 and the loyalty of its user base," said Kevin Taylor,
Digital's UK and Ireland OEM business manager.  "The appointment of
Mentec is aimed at providing continued sales and technical support for
those users of PDP-11 technology, allowing them to continue
development and use of the PDP-11 based systems and applications.

"In addition, Mentec works with VAX and Alpha AXP technology, making
them ideally placed to assist those PDP-11 users who wish to migrate
to Digital's newer technologies and make use of evolving industry
standards, open systems concepts and the client/server style of
computing," concluded Taylor.

About Mentec Computer Systems

Mentec is a leading technology company with locations in Ireland, the
United Kingdom, Germany and the USA.  The company currently employs
200 people and operates in a variety of technical and commercial
computer markets.  Revenues for fiscal 1992 were approximately 35
million.

Since 1979, Mentec has had a strategic alliance with Digital as an
OEM.  During the past decade, Mentec has become the largest reseller
of Digital equipment in Ireland.  MCS has recently begun to focus on
Alpha AXP with the announcement of a 3m programme of AXP-based
product development.  As part of this programme, it will work to
provide migration paths for the PDP-11 user base.

MCS has a long history of experience with PDP-11 products - both
hardware and software.  In 1982, Mentec chose the DEC J-11
microprocessor to design and supply a range of high-performance,
single-board computers for the PDP-11 QBUS market.  These are in use
today providing control functions for power, manufacturing and
telecommunications applications worldwide.

Mentec recently announced a high-performance PDP-11 emulation product,
the M11.  This will significantly increase PDP-11 performance and will

SIFT NO:    1533
SUBJECT:    MENTEC appointed as sole distributor for PDP-11 products
FROM:       Graham McKenzie, TOEM Marketing
DATE:       6th September 1993

Background

    Over the past ten years, as Digital has announced newer technologies,
    many  of our PDP-11 customers have ported  their applications to VAX or
    other architectures. However, a significant PDP-11 customer base still
    remains, mostly in the embedded applications areas.

    Providing these customers with the level of sales and technical support
    necessary to prevent them moving to non-Digital technologies has become
    increasingly difficult. To address this problem we have  appointed
    Mentec Computer Systems as sole distributors for the PDP-11 product set
    in the U.K. and Ireland.


Mentec Computer Systems (MCS)

    Mentec is a high technology company with locations in Ireland, U.K. and
    the USA. The company currently employs 200 people and operates in a
    variety of technical and commercial computer markets and is now the
    largest reseller of Digital equipment in Ireland.

    Mentec has a long history of experience with PDP-11 products, both
    hardware and software. This includes the design and supply of J-11
    based single board computers to provide control functions for power,
    manufacturing and telecommunications applications world-wide.

Mentec activity and support

    Mentec will work with our PDP-11 user base to secure the PDP-11
    business from 3rd party threat either by offering continued
    availability and support for PDP-11 based technologies or by assisting
    the migration to newer Digital environments.

    To support this activity, Mentec have appointed Doug McKay, based at
    Mentec's High Wycombe office, as business manager for PDP-11 related
    opportunities. Mentec also has in place a PDP engineering group to
    provide hardware and software engineering support.

                                                      
Action

    If you have accounts currently using PDP-11 technology and wish to
    discuss the opportunities to develop or maintain their PDP-11 business,
    or any other PDP-11 enquiries, then please contact either Doug McKay of
    Mentec or Bob Sinnott, Digital's account manager for Mentec @DBO (7)827
