I hope this is considered apporopriate for this list, if not, I am sure y'all will let me know. :-) And, yes, it is about a truly classic computer. I am trying to restore my 1961 General Electric EF-140 Analog Computer. The insulation on all of the wires has basicly turned to stick goo. I would really like to rebuild it. Does anyone have or know where I might find a wiring diagram for this box? I got it thru National Technical Schools when I was about 11 years old and sadly, while it survived, my mother threw out all of the courses and manuals that came with the correspondence course I took back then. If someone has it but it's buried away, no problem. I just loaned it for a static display at the University where I used to work in the CS Department. I expect they will want to keep it for at least the Semester. On another note, it's good to be back on the list after many years away. I still have and use a number of systems that people here would consider more in line with their notions of Classic Computers. Some of you may even remember me. I was and still am big on PDP-11's and VAX. But I also have a number of old Micros as well (and some of the newer ones that try to bring the old flavor back like the Maximite and The P112.) bill
