My old school HP 48G

This is the calculator that went to almost every exam I took starting from Calculus II.

I gave the money to my friend Rosa who came that year to New York with her parents and bought it here, so the calculator is back home now.

Without this equipment I wouldn’t be here, its an old calculator but very powerful, and like the ipods nowadays, it was the calculator to have on my engineering school.

There were some who used Casio’s, or Texas Instruments, but they sucked balls cause they didn’t get to beam each other programs, or “exam references” 🙂

Go HP48G

Here’s an article on wikipedia about the HP-48 series
en.wikipedia.org/wiki/HP-48

From 3.7Mhz to 4Mhz CPU frequency depending on temperature.
32K RAM (Not expandable, since that was the 48GX which had 128K RAM)
512K ROM

Supported a programming language called RPL (Reverse Polish Lisp)

All the programming I ever did was more of functional composition than anything else.

This thing rocked to solve equation systems of many variables, plotting, and even accounting. If you know how to use one, you know you can be pretty fast, you just have to know reverse polish notation.

Everybody had one of these in my school so you had to tag it somehow, it came with a blank metal plate.

My full name was engraved in the city of Guacara (Estado Carabobo, Venezuela), I have a cousin who used to own a sports shop, he had an engraving machine for trophies and the such.
