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.

Recently, I assembled one of the RX02 emulator boards developed by
AK6DN. I am using it presently in a BA11-M box with PDP-11/2 cpu
(really basic 16 bit system). I put the disk images from github on
the SD card (RT11 V5.07 and XXDP not sure what version).
The box has a BDV11 bootstrap / terminator board and I use this to
boot the RX02 emulator. Works fine when I boot RT11, however I can't
boot XXDP - it halts at 000104.
Do I need to use a different version of XXDP to run on the PDP-11/03?
