    I don't know about the 86 specificly, but earlier TIs (57?) used ROM 
    cartridges for specialized programs. I had one that did navigation and 
    piloting calculations,
    including sight reductions.
    One great thing about it was the documentation. Each function had a section in 
    the book that stated the algorithm in use, and gave sample forms for 
    recording data
    to enter in the program. The sight reduction program would store a series of 
    sights in RAM and automatically move them to the latest for a running fix, if 
    you gave it
    the DR info.
