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.
