XXDP on PDP-11/03

[Jerry Weiss]

There are two versions of XXDP+ V2 monitors.   The XXDPSM.SYS is needed 
for cpu's w/o MMU's or don't have more than 28KW.  This and XXDPXM.SYS 
are both on the AK6DN diagnostic image. However, only a few other 
programs exist on the image.

In SIMH the AK6DN image does the same thing.  The halt location 100 is 
near the LTC vector.  I turned BEVENT off and it boots successfully.
I am not immediately sure why this is necessary.
