Kirk has a TI-86 and TI-92 that work and a busted TI-85, although the
TI-86 is the only calculator that he has written many programs for.
Recently, he has shifted his attention away from calculators to other,
more important things. One day Kirk saw that ticalc.org needed dedicated
review writers and submitted a review for Sqrxz.
Kirk has now left ticalc.org for other projects.
