Apparently I fired off my original reply prematurely. The original MIT
machine running ZORK (MIT-DMS) was, in fact, a PDP-10. But I'm quite sure
that one of the other machines back there (i.e., MIT-AI, MIT-MC, or MIT-ML)
was an SDS Sigma machine (or even an SDS-940).
Sorry for my mis-informed post. :0
