RE: Your First Handheld?
My first was a Casio FX702P Programmable Calculator with FA2 Tape Recorder Adapter & FP10 Printer. I still have all of the above (in working order) and use the calculator almost every day. These were purchased sometime in 1981 were used for a variety of small, repetitive programmable calculations in a engineering company. Much handier & cheaper than the IBMs of the day[/font]

RE: Your First Handheld?
The first calculator I remember using was a NS 600 4 banger. I remember it used a type of rpn, but used the + key as an entry separator. I used a Rockwell calculator in Jr. High and High School and a TI30 in college. I remember my class mates on the G.I. bill all using HP 21s. The instructor used a HP 45. I was so envious.

RE: Your First Handheld?
My father gave me a Casio fx 7000 g when I was 14. He was a math teacher and wanted me to have a graphing calculator. I made my first programs on it and used it all through high school. When I started studying civil engineering her capacities were quickly overrun, so my mother gave me a TI85, which got me through college and I loved, although I wanted much more memory space to store my programs. After college I bought many other TI models (83+, 84+, 86, 92, 92+) mostly to satisfy some curiosity, but kept hearing about this wonderful hp calculators, so I got a 50g and after learning RPN I became an absolute fan of old hp models.

RE: Your First Handheld?
My first handheld was a Texas Instruments SR51A which I drove 90 miles to get. This was the first calculator I could afford. Several years later in the early 80's I upgraded to a TI58C and a year later to a TI59.
In the mid 80's I purchased my first HP, an HP15C. The keyboard after years of heavy use finally broke, but the batteries never needed replacement. After that I purchased an HP48S, an HP48G and in 2001 an HP48GX instead of an HP49 (I despise rubber keys). I upgraded to an HP50G when it first came out, but I still have and use my HP48GX with a 128 kilobyte ram card and a one megabyte ram card.

RE: Your First Handheld?
My first calculator but really not my own calculator just borrowed
from my stepsister. She used it for her university classes year 1989. At that time I was in 11 grade High School. That calculator is the Casio fx3900P Programmable. This calculator is my first to learn how to program by reading from the user manuel. At that age I'm really surprise that somehow I want to learn on how to program just because I wanted to cheat on the Math Test. I'm trying so hard on programming the problem of "Three Linear Equation of Three Variables" doing so by using the steps shown in the School Algebra Math book using the Matrix solver algorithm. Writing and Test for bug in program and finally success. So I use this to take a test that I did it very fast way too fast than other students in class, the test require to show the work on how to get to the answer so I just show fake work on paper because I known that teacher will not read all the work on each paper so I got "A" on this class very easily. Later on I was thinking over this and realize that in order to make any program one must know the Algorithm deeply to understand each and every steps. Once you finish a program then you really understand all of it and that will even make you remember it forever too. About a year later my stepsister changed course to a Business School MBA classes and this time she got the HP12C I sneak around in her room found this HP12C and quickly trying to play around with it but its not work as expected so I though that this calculator is broken and never think about this calculator in a long time. About year 2016 somehow I was refreshing my memory about HP12C I search the internet to learn everything about HP12C and get the real HP12C app for Android to learn from it. I see many interesting stuff that HP12 can do so I make a purchase from Amazon and I got the HP12C+ Then got the HP11C and HP12C Platinum Remark: I end up using the HP because of the RPN programming instead of the Casio BASIC programming style.

RE: Your First Handheld?
My first calculator was a Christmas gift from my dad in 1994 when I was in 4th grade. It was a TI Hot Calc, a brightlycolored 4function calculator which I used all the way into middle school. If memory serves, it was packaged with a drawing compass and protractor, both now long gone. I still have the calculator but it's definitely showing its age and the ON/C button is iffy. Fun times.
See a picture of one here: http://datamath.org/BASIC/LCD_Modern/ZOOM_HotCalc.htm First calculator I bought with my own money (saved from recycling aluminum cans) was a TI30Xa in 7th grade. Still have that one too.
