Well, either that was transcribed incorrectly, or the person who wrote it
confused. On the M8192, per EK-KDJ1A-UG-002, pg. 2-1, W_5_ is the halt trap
option, and W9 is... BEVENT recognition. One removes W9 to enable the LTC
(using the QBUS BEVNT line).
Which kind of explains your results... :-)

PS: BTW, the M8190 (KDJ11-B) in similar - the onboard ROM diagostics barf if
the LTC isn't on (i.e. the switch on the chassis to enable BEVNT has to be
on).
