I grew up between the northeastern hills of Hungary. My original profession was not the software development, but after I'm finished the secondary school I corrected this mistake. :-) I was interested in the microelectronic circuit like how the radio, digital clock works, So I learned microelectronics in an industrial school. My favourite theme was the digital technics. At those times I dealt with to build of basic electronic circuits with discrete 74xx integral circuits. I also built a digital quartz clock, (circuit diagram and PCB. here.) developed the circuit of the clock timing for a quartz based oscillator dividing the frequency 1Mhz to the base 1Hz (time base) which was the input of the counting circuit. Later my interest turned to the computer sciences, first I was interested in the hardware, later in the software development.
