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? -Henry -------------- next part -------------- An HTML attachment was scrubbed... URL:
