It wasn't a success, admittedly, but it did sell in some numbers. (I at one time, had four 11/60 machines to play with in a computer club, and I still have a complete CPU board set for an 11/60 - no WCS though.) The limited success of the 11/60 was due to the totally incomprehensible decision to go for 11/34 feature parity at a time when the 11/70 had already set the future standard. But apart from that stupidity, it was a rather nice machine, in a very nice package. I agree; I like 11/60s quite a lot. My very first computer consulting gig involved selling and installing a (very) used 11/60 to a private school in NJ. I wonder what happened to it. I really liked that machine. Its only real limitation was the 18-bit addressing, and I was really coveting the WCS capability! (my home machine at the time was an 11/34) 18-bit, no supervisor mode, and no split I/D-space... Just like an 11/34. Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B. Idol
