That is what happens here too... My guess is it is necessary to build a modified TOPS10.REL. But without the docs it can be quite difficult.= I have had communication from a PDP10 expert who makes me think it is *much* more complex than just rebuilding the monitor. The DMR11 may well have been in the PDP11 front end and I am not sure how that is done in SIMH at the moment. Regards Rob
