I was talking about DMERT today and Larry McVoy was wondering if it slipped out in any fashion.

I believe there were official trainers as well as a production emulator that ran it on Solaris/SPARC.  I have never seen them anywhere.  Old phone phreaks I’m acquainted with had illicit access. Does anyone know if source or the trainer or emulator are tangible?

I enjoyed the BTSJ on DMERT as much as the Unix articles.  Highly recommend reading.
