First calculating device of my own (1974): Picket N902-ES simplex trig metal slide rule

First electronic calculator (1976?): Cannon--I don't remember the model number, but it was only slightly beyond a four-function, definitely not a scientific, let alone a programmable. Its display was fluorescent, green (not blue-green, although it might have been because of the filter over it). It was a gift. I would not have gotten it myself.

First programmable of my own: TI-58c (Dec '81) later replaced with the 59 plus printer plus several modules and applications books. The HP-41cx came a few years later (1986), specifically to control instrumentation on the workbench.
