Pascal and the HP48SX/GX : and they lived happily ever after...
avatar
The first love of my live was a HP 48SX.

This is the machine on which I learnt to think sequentially. This is the machine on which I wrote the program which confirmed to me some side effects of gravity, such as the gravitational slingshot. This is the machine on which I learnt to count in binary, octal and hexadecimal. This is the machine on which I wrote my first machine code program (not the assembly, the actual machine code) and later on this is the machine on which I have written a much more complexe machine code program to simulate John Conway's Game of Live. This is the machine on which I wrote an implementation of the RSA's encryption schema (still in machine code -- took me 2 weeks). This is the machine on which I understood CPU registries (the Saturn --name of their microprocessor-- has got 64-bits registers). This is the machine on which I wrote my first computer virus.

This is also the machine on which I re-learn counting and leant the Reverse Polish Notation. RPN became more natural to me (and is still more natural to me) than the "middle operator" notation.

I have always regretted the fact that the one that I had, died after a while. But today, ladies and gents, the HP48 is back in my life. I have found a Mac port of it; and it would be a true understatement to say that I am very happy. I am EXTREMELY happy...
