    You are partially correct. AIX (Advanced Interactive eXecutive) was built
    by the Boston office of Interactive Systems under contract to IBM. We had
    a maximum of 17 people in the effort which shipped on the RT in January
    1986.

    Prior to that time, Interactive Systems had produced a port of System III
    running on the PC/XT called PC/IX which was sold via IBM. I used PC/IX to
    produce the software only floating point code in the first version of AIX.
