My first programming platform was basic on the Casio FX-702P, I remember reading the manual and realising what programming was all about... oh the sense of wonder and possibility on a 9 year-old. The peak of my achievement was a version of E.T. for it (my cousin had an Atari 2600 and to my little brain that was a pretty cool game). I saved my programs by writing them down on a notebook, as my dad never got any peripherals for it...
