I couldn't access this on my phone - no FTP client - so I blindly assumed
that it was DEC Technical Journal Vol. 8 no. 3.  That turned out to be
completely untrue, but in a perhaps amusing way - one of the articles was
Bob Supnik discussing the reasoning behind the original development of
SIM(H), intended to preserve computing history.

As far as the article you posted - from Vol. 4 no. 3 - the idea that 35
prototypes were created in ECL and running as a multiprocessor system,
taking over 4kW not including the front end, is absolutely remarkable to
me.  Does any of that original code for the front end still exist?
