Hi, all:

John W Kercheval Wrote:Your First Handheld?

In chronological order starting from 1975 or so:
  • Sears 4-function (not even square root !): very expensive, algebraic, did a lot of ersatz programming with it, electrically broke two times, expensive to repair.
     
  • HP-25: very expensive, did tons of programming with it, learned to love and worship classic RPN, incredibly powerful little machine for its time, ran rings around the impressive-looking HP-55. Never gave any problems but had to sell it to buy the HP-67:
     
  • HP-67: very very expensive, more than double the price of the HP-25, did even more tons of much more complex programming with it, the physical machine I've loved the most. Never gave any problems but had to sell it to buy the HP-41C (I regret it to this day but there was nothing else I could do at the time).
     
  • HP-41C: very very expensive, about the price of the HP-67 but you also needed to buy a very expensive card reader and at least one RAM module to just be able to run your HP-67 programs. First alphanumeric, heart of a system with many peripherals. Did even more tons of much more complex programming (synthetics included, I did a lot of research on my own) but never liked it as much as my beloved HP-67, matter of fact sold it twice and never got another till 20 years later exclusively for collecting purposes. Physically it didn't hold a candle to an HP-67 but never broke on me.
     
  • HP-11C: Given to me as a present (Hi, Fernando !), I loved it, its form factor, its capabilities, its 10+ years running on a single set of batteries. Wrote a number of programs for it but mainly used it for manual calculations. Carried it with me to scorching and dusty climates and never broke on me, I still have it and it still looks mint and works like a charm.
     
  • SHARP PC-1211: amazing affordable little machine, first model programmable in BASIC, I loved it, physically much more attractive and sturdy than the HP-41C, much better LCD (much longer, dot matrix instead of segments, much more readable) but worse (though still acceptable) keyboard. Excellent documentation including lots of full programs. Did a lot of programming with it (about 100 programs) and found it extremely easy to program and use. Never broke on me, sold it to an enthusiastic pal but regretted it.
     
  • HP-71B: extremely expensive and powerful handheld, programmable in a tremendously powerful version of BASIC, tons of peripherals, ROMs, RAM (up to 512 Kb addressable), lots of extra possibilities (FORTH, Saturn assembler, FOCAL). Did a lot of programming with it and I still use it all the time, in emulated form. Never broke on me, never sold it and matter of fact acquired many copies for collecting and presenting it to friends.

After these, 20 years passed by and I went into modest collecting so right now I own 100+ machines including HPs (all Voyagers, 41C, 42S, 71B and many more), SHARPs (about as many) and assorted (some CASIO, TI, etc) but I do not use them in physical form anymore except for the HP-15C and the SHARP PC-1350 which I use for manual calculations or simple on-the-go programming.
