|I just had my first hp3000 crash.  Seems it received a parity error.
|The specifics are listed below:

|Parity Error
|B=26
|A=056772
|**** System Failure #13
The B stands for the bank number in which the multi bit error occurred. 
The A is the address of the error within the bank. Both numbers are in OCTAL.
A multi bit cannot be corrected as single bit errors, hence the crash. You can
figure the memory board responsible by knowing that there are 8 banks per 1 
megabyte of memory. You may have 1/4 meg, 1, 2, or 4 meg boards (they are
marked on the board). I wouldnt panic over 1 occureence but I would run 
MEMLOGAN.pub.sys and check the memory logs. If there are any logged errors
on the same board as the failure, I would consider replacing it proactively.
In your case the problem is on the 3rd meg of memory or board 2 if you have 
all 1 meg pcas.
