I'm employed as a professional software developer. My first machine code experience was on a Commodore 64 (6510 processor) in the early 80s I think. Later Motorola 68000 (AMIGA 2000), Intel 80186 and SATURN (on the HP48SX calculator, I reverse engineered the whole operating system, that was 1992).
I'm supporting some users on the GSM Forum pages regarding jailbreaking etc.
