Hi List,

I have a working 11/84, and I have decidec, to test some of my spare 
cards, starting with: KDJ11-B.

I see the following error, when powering up the system, which points me 
to the Clock.


 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Error 61
M8190 clock Error

See troubleshooting documentation


Command    Description

    1       Rerun test
    2       Loop on test


Type a command then press the RETURN key:
 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Any hints, what the problem could be? Is the clock in this new PDP's 
still generated out of the line frequency? Could it by, that the KDJ11-B 
is configured to a wrong HZ value?

Many Greetings
Ulrich
