Old Newbie

leviset

Just joined this community. I’m a retired Pure Mathematician aged 70. I started my first IT job in 1979, programming an HP-97 Desktop Programmable Calculator and then in 1982 I was in the very vanguard of the PC Revolution working on a Sirius 1 computer running under CP/M 80 & 86 with an Intel 8088 & 8086 architecture.

Since retiring early in 2004 I’ve gone back to my early vintage programmable days using calculators like the HP-41CX, TI-59, Sharp PC-1500/A etc.

I’m fine on the Pure Mathematics and Algorithms side but rubbish on the application side of electronics - the main reason I’ve joined is to try and improve my overall EE skills

  • Welcome. My tree rings do not exceed your count but the year you started IT was just shy by two years of when I started a career in electronics. I built my first pirated apple IIe not long after.

     

    Your Ti calculator reference caused me to remember my Ti-66. That sucker saved my bacon in the high arctic by doing 2 cycle analysis on RF waveform readings avoiding the painstaking task of performing the math manually.

     

    I do recall a civil engineering friend of mine playing a game on a calculator similar to yours. The game was to land a space ship on a planet by entering rates of fuel burn. You had to adjust the fuel burn to reduce the vertical velocity of the space craft. Hit the planet to hard and the ship was destroyed. No graphics provided just changing numbers on a calculator screen. I never ever successfully landed but my friend got very good at it. Evne to this day, not much of a gamer.

     

    Thank you for triggering a core refresh of brain cells I thought had atrophied.
