KA630, KA650, KA655 CPU bulkhead pinout?

» close window

The Question is:

 
I have a KA650 that is missing the bulkhead, where could
I find the pinouts of the connectors that goto the bulkhead, (make my own
bulkhead) technical scematics/pinout charts would be helpful, and I am
currently doing with out manuals because they were lost in a fire 3 years
ago... Any help is appreciated... ev
en a url for the information... and I have already looked at the faq and
vax1 and misc1 are useless since they tell the function with out the
pinouts...
 
Thank You
 
 

The Answer is :

 
  The Wizard does not recommend working directly with the CPU modules, the
  connectors, or replacing components or bulkheads unless properly trained
  and equiped -- these can be static-senstive and can easily be damaged.
  Failure to correctly wire the components -- or any potential (pun intended)
  errors that might be present in this message -- could lead to equipment
  damage.  Further, there are potentially hazardous or even lethal voltages
  present inside system enclosures.  The Wizard strongly recommends that all
  service be refered to and performed only by qualified and appropriately
  trained personnel.
 
  The Wizard would strongly recommend acquiring a used MicroVAX II (KA630)
  system, or a system with a non-functional KA650 or KA655 processor.  These
  systems all use compatible bulkheads.
 
  The bulkhead pinout is documented in the KA630, KA650, and KA655 technical
  manuals.  EK-KA630-UG is one of the associated manuals.
 
  Configuration and display connector pinout:
 
    01, 02, 03: ground
    04, 05: zero for arbiter CPU (default), non-zero for auxillary CPU
    06: ground
    07, 08, 09, 11: display register bits (10 is MSB, 07 is LSB)
    10: battery voltage
    12: ground
    13, 14: boot-diagnostic code
    15: halt enable
    16: ground
    17, 18, 19: baud rate selection (19 is MSB, 17 is LSB)
    20: fused +5V
 
  SLU connector pinout:
 
    01: reserved
    02: ground
    03: output from CPU to SLU
    04: ground
    05: ground
    06: key; no pin
    07: +differential input to CPU from SLU
    08: -differential input to CPU from SLU
    09: ground
    10: +12V fused (for DSR)
