The TI-86 is the best calculator ever made in my opinion. |

My first calculator was HP 21 back in 1975, once I got my head around RPN it was amazing what you can do with 4 level stack. Nowadays I don't use calculator very often, I got HP 32SII for more demanding tasks and for casual use I got Real Calc on my phone (in RPN mode of course). I find after getting comfortable with RPN I can use algebraic entry calculator but it requires extra effort and it's slower for me. Got a bit of soft spot for old calculators, mainly HP but other too. Have a few HP 21's and some others from 1970's, most of them bought junk from Ebay and restored to working order. There are few more waiting to be repaired including Casio from early 70's (4 function office calculator with VFD display) and abused HP 28S which may be beyond restoration. |

In my progression from the hp25 to the hp48GX (and every single model between them) I used to carry my hp97 to work every day in my breifcase. Magnetic card reader to load programs, soft keys that lined up with the magnetic card, built in thermal printer, pure calcualtor porn. ;D I still use the 48GX every day in the shop. I hate the 50, it is unuseable compared to the 48. |

Nice, do you use the paper tape feature? Can you still get inked-ribbon for it? I see they occassionally sell them but its nearly $45 for a ribbon cartridge! http://www.staples.com/HP-97-Tricolor-Ink-Cartridge-C9363WN/product_573985 --- Quote from: robrenz on August 23, 2012, 01:05:47 pm ---In my progression from the hp25 to the hp48GX (and every single model between them) I used to carry my hp97 to work every day in my breifcase. .. --- End quote --- |

I did not keep all the intermediate calculators, I sold them to friends and coleagues as soon as I could buy the next generation. The printer on the 97 was thermal. I actualy wrote a 97 program that generated gcode for our cnc lathes before there were readily available CAM packages. I had 3 people using the same program on hp41CX's cranking out gcode to manualy punch into the controls. Also did a program to do helical interpolation before it existed as a command on the cnc controls. Many a thread was milled using that program. Those were the days ;D |
