This is both a supplement to my lecture on Fluid Mechanics Laboratory Video: Least Squares and Curve Fitting and a trip down memory lane for those who used TI calculators in general and this one in particular in the late 1970’s.

I was working for Texas Instruments at the time this calculator was in production, albeit an earlier version. But I was not working on calculators for TI but was working on the HARM AGM-88A Missile.
