What was it? Mine was a TI-59.

Others? Anyone use a Timex? Altair?

My "first" electronic hand held calculator was a APF Mark25/Memory four-function model purchased in the spring of 1975, when I was 13, for around $30. I had wanted an electronic calculator since I discovered they existed around 1973 but it took me 2 years to convince my mother that buying a calculator would not ruin my ability to perform math by hand!. My second (and my first scientific model) was a Commodore SR4148R around December of 1976 for$65 (Sears). This model had 48 keys! I had already learned about HP calculators by this time and was lusting after the HP-25, but I could not afford it.

My next (and my first RPN calculator) was a Novus Mathematician I was given (free) in early 1977. Although it gave me my first taste of RPN, the three level stack, lack of scientific notation and missing instruction book was a big obstacle to using it. It just teased me more about getting the HP-25 I wanted so badly.

Somewhere around this time I bought and assembled a Sinclair Wrist Calculator (not a watch). Although it worked, it had mechanical problems and went through six expensive watch batteries quickly.

Finally on June 12, 1977, I purchased my HP-25 for $116.00 (plus tax) from a "Calculator Store". The rest is history, as they say. I have owned many calculators since then but only use HP's for work or for "serious" play 05-07-2014, 08:04 PM Post: #4  walter b On Vacation Posts: 1,968 Joined: Dec 2013 RE: Your First Handheld?

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. http://WilsonMinesCo.com (Lots of HP-41 links at the bottom of the links page, http://wilsonminesco.com/links.html ) 05-07-2014, 08:33 PM Post: #6  Brad Barton Member Posts: 181 Joined: Jan 2014 RE: Your First Handheld? Mine was a Texas Instruments SR-10. It was on sale for$60.00 and I talked my dad into buying if for me. Must've been 1973 or so. The next week it was down to \$40 and a few weeks later discontinued. Ah the march of technology. My dad's face when he saw the price dropping --> D: It's long gone, but I picked up another example a few years back.

I had a few more TI's and Casio's until I broke my 3rd TI-55 in college and got sick of buying more crappy calculators. My buddy had a 41C, so I looked around and picked up a used 41CV about 1982 or so off a policeman who was using it to calculate speeds for drivers. He'd time them between two points, put it into the CV, and decide whether or not to give them a ticket.

Unfortunately for him the 41CV was too much voodoo for the court system at the time, and his tickets kept getting thrown out. He was forced to sell it, and his loss was my gain. I still have it after all these years, and it works flawlessly. Eat that TI!

Hmm... A Casio Digital Diary - SF-3500 I think - when I was in the first grade. I was a weird kid. I'm no less weird now.

Privileg 883 D-ESR-E, maybe 1977. Non-programmable scientific with green display and no shift key, even inverse trig functions had their own key. Still works, but has key bounce issues.

Later came a Ti59 (in 1979) and that was the last pocket calculator that I really used for it's purpose. After that, it was Lotus 123, Excel, the mobile phone and the iPad. All my other 998 or so calculators, including all the HPs are really only collection items.

An SR-16-II for Christmas.

Dad had brought home an SR-11 at one point to show me and a Berkey 2030, but the first I had that was "mine" was an SR-16-II. About 10 months later I bought an SR-51A, which was much more capable.

Then an SR-52 (used), a TI-58C... right when the HP 41C was announced...causing me to return the TI thing. :-)

I got an HP 41C and never looked back.

These were my first, second and third (for those who can read it :-) real handhelds. The previous TI-51-III and TI-59 definitely don't count!

I think it was a Casio FX-300MS.

Went from that to a TI-83+, then a 50g (having learned about RPN, I played with a third-party 4-level implementation for the 83+, and decided I liked it. Then, when it came time to get an RPN calc, I couldn't justify a 48-series machine against the 50g, couldn't justify the 33s, and couldn't justify any of the older 4-level machines for the price), then everything since has been 4-level machines.

In 1970, as a junior in HS, I used a Sterling 684 slide rule.

During my years in the Navy I did any calculations I needed to do by hand.

In 1977, when I started college as an engineering student with limited funds, I used a TI-30. After a year the keyboard started acting up. I upgraded to a TI-58.

Two years later the keyboard on that one started to go too, and I was strongly considering a TI-59 and printer cradle, but the alphanumeric capabilities of the
HP-41C won me over. It's been HP ever since.
