Computer Magazines with Source Code
I have to thank my older brother for getting me into computing after he wrote a simple for..to loop saying "my brother is a w@$ker". After that I just had to learn how to get my own back. It was so much fun that I forgot why I even wanted to learn. When I was 12 I learnt so much debugging the crap that was printed in those magazines. This kind of stuff should be available to today for children. At that time you would would buy the mags for the games because there weren't any ready games available in the shops. Those mags also taught you about machine code too. I learnt 6502 and Z80 machine code on the PET and the ZXSpectrum from those mags. We had to wait a couple of years for assemblers to come out. The machine code came in useful many times afterwards when I was working as an electronic engineer.
