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?

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.

That sounds like it is trapping due to an LTC interrupt. Turn off the LTC
cheers,
