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

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?
